Bought myself a dusty Zeiss Ikonta folder with a really busted and torn never ready case(in pieces), turned out to be a Zeiss Super Ikonta IV with a 75mm 3.5 Tessar lens! woot! Got the shutter to fire once by bypassing the plunger and tripping the latch on the lens barrel, but It wouldn't cock to fire again. Really small and dirty rangefinder though, but Im excited, sending it out soon to get it repaired and in shooting order. Hopefully its not too expensive!
