Thanks for the link, Len. All kinds of good stuff there.Len Robertson said:"... This page http://www.cameraeccentric.com/html/info.html has scans of B&J catalogs..."

Jim Jones said:Brad, the device in the upper left of your photo is , like Jim Galli says, a solenoid to trip the shutter. The solenoid doesn't fire the flash. A switch on the flashgun fires both the solenoid and the flash. There are also contacts in the shutter to fire a flash. An adjustment at about the 5 o'clock position of the face of the shutter changes a delay in the shutter for either F or M class flash bulbs. The shutter wasn't designed to fire electronic flash, but altering it to do so is fairly easy. The two posts near the flash adjustment are the flash contacts.

You are certainly right. I misread X for M. The old F-M and X shutters may have been produced concurrently for some time. The X shutter might be preferred for studio strobes, but the F-M sync was still needed for photojournalism.Lachlan Young said:Having gone away and looked at the shutter on my Speed Graphic I have discovered it is a SUPERMATIC X shutter - ie strobes only yet it has the same style of flash contacts. According to the CAMEROSITY (1,2,3,4,5,6,7,8,9,0) system the lens on my camera has the letters ES on it - meaning the lens was made in 1947 - if it is the original lens on my camera then it dates it to the first year of Pacemaker Speed Graphic production! Using the CAMEROSITY system it should be possible to find out the age of the lens as well as finding out approximately when the Supermatics changed from F or M sync to X sync.
Hope this helps,
Lachlan
DBP said:One more thing. On the top left (photographer's left) corner of the body near the back there may be a very small catch, which allows you to release and rotate the back. I don't know if all B&J Press cameras have a rotating back, but mine does.
JiminKyiv said:Mine doesn't. BTW, I do prefer it over the Speed Graphic I used to have. The metal body is much more useful in an emeregency - wheel chock for a 747, for instance, and it will leave a bigger dent when dropped on pretty much anything.
On a more serious note, if yours is like mine, you'll find out that the front can drop about 15 degrees below horizontal. This is good. Ignore it for now - use it as a big point and shoot for the first little bit, then play with the movements.

The lens date may not be a good indicator of when the synch changed. The Supermatic my 1944 Ektar is in is also X-sync, but was probably adjusted at some point in its life. Has a PC contact too, so apparently there were many options, including no synch, which is what the rest of my 1940's shutters have.Lachlan Young said:Having gone away and looked at the shutter on my Speed Graphic I have discovered it is a SUPERMATIC X shutter - ie strobes only yet it has the same style of flash contacts.
