I'm impressed -- whatever shipping service the Japanese seller uses (from what's described as an outlying island) is apparently very efficient, and USPS was seemingly having a good week, too. I was told to expect delivery by December 14 -- and today, a full three weeks earlier, there was a very solid and well-packed box from Japan with my Mamiya 6 inside.

It's sixty-five to seventy years old, near as I can tell, yet the only things I can find that don't look 100% are the format window selector on the inside of the door is missing its knob (works fine with a pen tip or small screwdriver inserted in the hole it came out of) and one edge of the rubber light control cup around the red windows is cracked. I don't anticipate light leak problems; any light that escapes through that crack will still land on top of the slip-in backing plate. If I don't leave the camera sitting in direct sun with the window cover open, it'll be fine.

And that leads up to: the leatherette is fine, all the glass is clean, shutter appears accurate on 1, 2, 5, and 10 and sounds good on faster speeds (up to 300). The self-timer almost works -- it runs about halfway under its own power, but then needs a little gentle push to finish the trip. I'll avoid using that in favor of cable release. RF patch is bright and clean, and the scale appears accurate (in feet, no less) -- won't know about the image focus until I process the first roll, obviously, but it's a well protected mechanism, inside the body, vs. external moving parts that also have to fold up with the bed.

I'm not sure which version this is -- clearly not an Automat, nor the one with a frame counter, it's red window all the way. No forgetting which one to use, though -- set the inside selector when you load, according to whether you put the flaps in or out, and only the appropriate window will open. The lens is a Sekor T 7.5cm f/3.5 -- not quite as impressive as the f/2.9 Tessar on my Super Ikonta, but this camera wasn't built to be a night shooter (and yet could still be, with modern super-fast films like Delta 3200, T-Max P3200, or even XP2 Super pushed two stops and bleach bypassed), and Sekor lenses aren't junk by any definition.

Once I finished function checking, I loaded up a roll of Portra 400NC (fresh when I bought it in 2004 -- everything else around it has been okay), camera set up for 6x4.5. Shouldn't take too long to go through sixteen frames, and I might even manage to print one or two over my upcoming 4-day weekend.

Pictures, pictures....lets see it!

Let's see what I can manage...

Okay, too many steps to post tonight (bedtime in about twenty minutes, have to save the pictures from my phone to Dropbox, download to my computer, and resize them to fit here). Meantime, until I can get that done, you can look over the original eBay listing.

I have one of these exact cameras (6x6 and 6x4.5 version). You are going to love it. Worth every penny, and then some.

Thanks, @Ariston I tried to buy an Ensign Commando first, but the one I could afford turned out to have been either dropped on its accessory shoe, or otherwise smashed up -- top cover deeply dented, RF non-functional, and frame counter seemingly not working. The Mamiya 6 appears to be at least partly copied from (the concept of) the Commando -- a dual format folding RF camera with a very rigid front standard achieved by moving focusing to the film plane. The Commando came out in a military version in 1945 (just missed the war, so not many of those around) in 6x6 only, then dual format civilian version in '46 with an upgrade in '48; all versions had a frame counter (how they managed that in dual format is a mystery to me). As far as I'm aware, the 6 was first offered after the Commando was out of production, and most of them didn't have a frame counter -- though to be honest, the counter in my Super Ikonta B isn't perfectly consistent, whether due to wear or just slop in the gear train, and if using the red (well, in this case more yellow) window is the price of getting one of these I can afford, I'm in.

I'm not familiar with the Commando, though I've heard of Ensign. I have a Super Ikonta, but the lens in my 6 is much better - sharper and much more contrast. I also find the 6 easier to use, of course, because focusing is easier.

I really am surprised that these cameras aren't much more expensive... especially with the price of film cameras these days. But people seem to prefer the newer plastic non-folder Mamiya bodies. I'm sure those are great, but they are also crazy expensive. These folders provide a crazy value.

I hope you enjoy it. Looking forward to examples.

Sigh...

Finished the first (test) roll today, went to unload the camera -- and found one of the knobs you pull down to disengage the pin from the spool had fallen off. This camera didn't come with a case of its own, and the knob isn't in the camera bag I've been carrying the camera in, or, as far as I can tell, in my car (though a car is difficult to search effectively for a small part, especially a non-magnetic one). The two knobs are the same -- verified by unscrewing the supply side knob and temporarily installing it in the takeup side to let me unload the exposed film. I'm not very interested in paying $90 including shipping for a parts camera.

Presuming I don't find the knob (if it came off at work, it's gone; the lunchroom, shop, and warehouse will have been swept/mopped by the time I get in on Monday), does anyone happen to have a spare off a non-functional camera, or know the correct thread? Presumably metric, fine pitch, but I can solder up a usable knob from a brass screw and a couple washers, if necessary -- and if no one happens to know, I can apply magnification and count the thread myself.

mine is not quite that old and also in good condition.to me it's the perfect MF travel camera but I had to have Mamiya adjust the focus for the 150mm lens,which they did for peanuts!

What? 150mm lens? I think you're talking about the newer Mamiya 6, the non-folding one. Mine is the folder, 75m f/3.5 Sekor T and that's what you get (though it was apparently also sold, over its run, with a Zuiko D. or Kantar with the same dimensions).

Photo of knob? setup? There might be something from another camera that will work.

I'll get a photo of the one I still have today. Critical dimensions are the thread diameter and pitch and shaft length.

Okay, here are photos previously requested (finally had time to upload from my phone to Dropbox, open in GIMP, crop, resize, and save back to Dropbox).

The camera as I received it:

IMG_20201123_193525.jpg IMG_20201123_193548.jpg IMG_20201123_193621.jpg

And the missing knob and remaining (identical) one.

Bottom of the camera showing where the missing knob should be; inside parts (in a bag so they won't get lost), remaining knob showing light trap cup, shaft, threads, spring and inside pin, and remaining knob in working position.

EDIT: did I mention the main reason I quit thinking about shooting DSLR (after using a couple old Nikons for a year or so) was because my phone was a better camera than any DSLR body I could afford? Film is still better, though, if you know what you're doing.

Go to the hardware store and find a metric bolt that fits? Looks like 4mm, but maybe not. Hard to know what else you would need without the camera in front of me, but I'm sure you can figure it out.

At work, I'd call it a "shoulder screw" -- the thread is smaller diameter than the shank, and the shoulder screws tight against the inside of the cup in the inside pin. This and the cupped knob are light trapping features. I could load film by removing the knob from one side, loosely screwing in on the other, installing the takeup spool, then swapping the knob back to the supply side (tight, so it won't come out and get lost, too), loading and away I go -- but with the knob missing, there's a direct path for light to the interior of the spool. It might still be adequately trapped to avoid fogging (likely would be), but it would also take ten minutes or so to change film and the constant loosening and tightening of the knob could/would result in marring the pin on the supply side from gripping with pliers to get enough torque.

If I had my lathe set up, I could turn a near-exact replacement, but I don't have room to set up and operate my lathe or unpack the rest of the related tools -- and threading to a shoulder is prone to mistakes resulting in "start over". Not even to mention the fun times cutting a metric thread on a lathe with US thread lead screw.

Finding a (probably) 2mm screw long enough is very unlikely; I'd have to cut a longer screw, solder up bits of brass tube (if I can find any close to the right size) to center and solder in the screw, then solder up pieces to make the knob. Not impossible, and I'll pursue that option if I can't find a replacement, but getting the correct part would be much preferred.

I may try contacting the seller in Japan to see if he has any spares he'd sell me...

I think I would try to find a matching screw at the hardware store, then mount it in a wooden drawer handle - you know, the round kind where they put one handle on each side...

Wood would be easier to fashion into the necessary shape.

If this is the missing part:

You could probably re-created it with a shoulder bolt and a set-screw style knob. Just lop off the head of the shoulder bolt and attach the knob.

Correct, that's the part that's gone walkabout. As you say, a shoulder bolt either set into a knob or with the knob replacing the head (though I'd as soon solder or epoxy it in place, as depend on a setscrew) should do the job. Shoulder bolts aren't easy to find, though, and I need to confirm the actual thread before I order (because they're also not cheap, nearly a custom-made item unless you duplicate one used in a common machine). I'll check the fastener catalog when I get to work tomorrow, though -- if it's a more or less standard bolt, it'll be easy enough to change the head -- solder on a washer with a piece of tubing for the outer rim, for instance.

Well, color me flabbergasted. :blink: Came in to work this morning, and found the missing knob/screw sitting on one of the tables in the break room. That's far from what I expected, but I'm very happy it occurred. I left the camera home today, but it'll be back in service a few minutes after I get there. :D

Nice. Love when that happens.

Had a cover/screw over the wind lever disappear from a Minolta CLE. When I noticed this, a couple of hours later, I backtracked my walk downtown. I had stopped for ten minutes to talk to someone outside a very busy ice cream stand. There it was, lying on the sidewalk between a storm drain and a very busy shop entrance. No idea how it didn't get kicked into the drain or stepped on and smushed, but I'll take it.

That is great news.
Reminds me of when I went to pick up a Durst enlarger from a shop that was closing. After re-assembling it in my darkroom a special screw for the table adjustment knob was missing. I went back the next day to the site and found the screw on the ground.
