Luigi,

 

Sadly these ventures of putting a number of companies together, some of which were already failing and with very different philosophies to "save the day" rarely seems to work.

 

Bull were a weird company. My parent company in the 1990's used their minis and a server as a central platform. At my previous company, I had been one of the directors on the IT panel. I had been working with computers since the mid 1960's and was therefore, not wholly ignorant of how they worked and more importantly how they didn't work. Anything we suggested to Bull, they just sadly shook their heads and said: "not work". Very different philosophy to IBM who were very cooperative  and proactive in trying to help you achieve your IT goals. Meetings will Bull were one of the things I missed least, when I sold my company and retired.

Well, I have a KB- 28 camera and along the way I found a copy of an article titled: "Everything you ever wanted to know about the KE-28B cameras and were afraid to ask.....".  Author Neil Levine, copyright 1982.  Possibly reproduced in Viewfinder magazine but I am not sure. The article is quiite extensive, especially redarding the ELC lenses and their specifications.  It also say that Chicago Arial produced 985 cameras, i think these were the A model, and that Maurer produced 932 of the B model.  It does not mention any transfer of production to ELC of the camera body.  Maured did have considerable trouble and the company eventually failed.  The B model had the new titanium shutter, the vacuum system to hold the film flat and the new and much better resolution ELC lens.

I also have the Operations and Maintance Instructions (Navel weapons bureau).  These documents should be availabe on line, if not I can copy them for you.

Hello good sir, I was hoping you might be able to share with me the maintenance manual if you still have access to it. I just acquired one of these cameras and after winding and firing off the shutter a few times it appears to have jammed up. I am hesitant to start disassembling the camera to inspect what may have caused it to jam due to a shockingly sparse amount of info regarding these cameras. It would be a boon to have the maintenance manual to aid in my repair endeavors.

thank you,

alex

The maintance manual doesn't really go into a complete  dissassembly, but does mention that a non-operational shutter can be helped by cleaning the curtain transfer tapes. PM me with an address and I can send the 25 page manual, to some locations. It is   NAVWEPS 10-10BH-3,   I couldn't find it easily on the web, maybe you can. Regards   If the drive mechanism is jammed, here is the diagram, good luck!

Alex, 

What has probably broken is this part below. It breaks when folks fire the camera without a film in it to slow the wind speed. I had a new one  3D printed for me in titanium - not cheap. I do have the print file which I can send you. The part "catches" the mechanism at the end of the wind cycle.

PS If you are going to work on the camera yourself be VERY careful. The spring for the clockwork motor drive is extremely powerful and unwary technicians in the camera's military days, have apparently had fingers severed by it.
