Just what the h*ll is this thing????
It`s got a WW2 (pre 1945 era) lens number - Maybe it was a prototype aerial photography lens?????? Something built for the military that`s for sure.
I think we`ll need a reinforced neck strap for this one and an accessory VF on the top plate, but even that would`nt work because the lens is in the way of everything!!!!

PS: I`m pretty sure this was mounted on a Aircraft camera housing, because it would be UNREAL on a Wartime era IIIC K - gee my camera would be lost behind this thing, but it would look pretty kool on a tripod don`t you think? - I better stick with a Xenon that`s fast enough! 😉
