I told this story somewhere recently: Last year I bought an ultra-rare Carl Zeiss Jena Universal Palmos, in good working condition, for around $30.00. The camera is from the first year of manufacture, 1903, only 15 serial numbers after a presentation camera I saw auction for over $600.00. The eBay seller didn't know what he was selling; he advertised it as a B&J because someone had grafted a grey-painted wood 5x7 B&J back to it. I was the only bidder!
I rebuilt the back (the original frame was there but had been modified to accept the B&J back) as a 4x5 (it was originally a 6x9, I believe) and put a nice Zeiss lens on a dial-set Compur on it, and took it out to take. It's built like a tank and weighs just as much. Otherwise I would use it a lot more.
I've asked several people for information on the camera, including the Zeiss website people. It was probably made by Palmos for Zeiss. Strangely enough I have two Zeiss catalogs that feature the camera, but know of no other examples except for the $600.00 auction camera. It is not mentioned in any of the Zeiss collectors lists posted on the web.
