Really old zeiss-ikon enlarger (medium format)

The Zeiss Ikon (no hyphen) enlarger appears to be a Miraphot, which was first made in the 1930s. I have two of Zeiss Ikon enlargers -- for 35mm and for 120.

I was going through some literature yesterday and came across a photo of what appears to be your enlarger. Send me your e-mail address through APUG, and I will scan it for you.

Is this the enlarger with the Rodenstock lens?

 

What numbers are on the Novar lens? I believe this is a medium format enlarger from the 1930s. It should keep its focus as you move the entire unit up or down to change the size of the enlarged image.

 

It looks pre-WWII, I just went to look in a 1935 BJP Almanac but Zeiss don't list an enlarger. Try the Zeiss catalogues on Photoeccentric.

Welcome to APUB BTW

My mistake, it's CameraEccentric

There's two Zeiss catalogues listed.

Yes, that's a medium format enlarger, and still quite usable.

The enlarger bulbs are no longer made, so I've converted my enlargers to use flourescent lights, which is fine for black and white.

 

Oh wait, that should be usable for 120 film and for other negatives up to 6cm x 11.5cm and even 9cm x 12cm, because it's a 13.5cm lens.

Zeiss Ikon's "D" cameras (6x11.5) used a 13.5cm lens. I think the 9x12 cameras, such as the Maximar, Miroflex and others, used either a 13.5cm lens or a 15cm lens as the "normal" optic.

 

I have the instruction sheet for Zeiss Ikon's 35mm enlarger -- the Magniphot.

I believe that the bulb you want is a PH211. You should be able to still buy them. I recall reading that they aren't being made anymore.

It was very easy to convert the enlarger to fluorescent.

 

The ceramic socket is probably original and should be replaced. The wiring should be replaced too, because 70+-year-old wiring could be dangerous if the insulation has dried and cracked.

I think they stopped making the bulbs, because demand had dropped. It cost them more to make than what they got in sales (no profit). No profit = no product soon.

You want the instant-on fluorescent bulbs, not those that take 30 seconds or longer to be fully bright.

This part is very simple. The fluorescent bulbs generate very little heat. Get a piece of translucent plastic and make a small shroud that will sit inside the enlarger head.

I'll send you some photos to show you what I did with my Magniphot. It works very well, and I've had no problems with uneven coverage.

Years ago with an Omega enlarger, I once tried a regular light bulb, and the writing that was on the light bulb was also on my print! I then removed the writing, and then while setting up the enlarger, I could now see the filaments in the light bulb.
