A&M 36" lens

greenspun.com : LUSENET : Large format photography : One Thread

Anyone out there ever hear of an A&M 36"/5.6 telephoto lens? I have one and have adapted it with a PVC tube, mount, the largest Packard shutter, and bellows to shoot 4x5, 5x7, and 8x10 (use it for detail shots). It is HUGE and HEAVY (7" diameter front element, 25 lbs.). All I know is what I have been told, which is that it is a military surplus, special order aerial surveilence lens. The f/stop numbers look almost hand-done as does the "A&M" corpaorate name. It has tested very well, though not ultra-sharp but this may be a function of the Packard or other variables and does not require much draw because of its telephoto design, but no one I know knows anything about it beyond the above. Who is A&M? Is the description accurate? When was it made? What have I got? Thanks.
