A parent at the school where I teach just ran into this camera and bought it for my "good old stuff" cabinet in the art/photo studio. It's a Kodak 3A Folding Pocket Camera, Model B-4. So far, so good. It has a regular back, a combination back, ground glass insert, two double plate holders and... and here's the part that seems weird... a 4x5 B&L Zeiss Tessar f6.3 series IIb lens, in a Koilos shutter ("Made in Germany" stamped in the aperture plate.) Above the lens, "B.& J." is stamped into the aluminum face of the shutter and that face is also decorated with what some have called Deco but I see as more late Art Nouveau patterns. Interesting gear in remarkably good, unrestored (read-somewhat dirty) condition. I have a few questions of the initiated, if anyone wants to step up and admit to being so. The format was 3 1/4 by 5 1/4. Can I fit 4x5 film septums in there? Has this lens got any history? I have a few tessars and like them, (most of my camera gear has come through the kindness of strangers and is ancient and honorable) but was the B&L connection a positive one in the Zeiss line? Sorry to be so ignorant, but I've found that Apug has invalidated all that have tried to teach for years about looking things up yourself instead of just asking others. I get so many fascinating bits of stuff when I ask anything here that I'm addicted to throwing out questions--- sort of like trolling. I've done the usual google or two but it seems an odd combination of lens, shutter and camera. Most are the Rapid Rectilinear type and I can't find too many Koilos shutters on Kodaks. Any info? Thanks in advance for any attention at all.
