Very nice, my Automat is a hand me down from my father it is from 1937, bayonet filters on the taking lens and push on filters on the viewing lens. The lens and shutter are fine, it seems to like shooting Rollie Retro 100 (APX100) developed in Rodinal, the old Tessar have turns out some fine negatives.
As for the reaction to changing the body cloth, I have never understood why folk get wound up by custom cameras, guns, cars or whatever. Each to their own I guess.
