During a long time there was no "screw" Praktica body on this site. Apart from this one, as an explanation!
I never was a "fan" of older screwmount Prakticas. Maybe because of their very cubic shape, and the "squared grenade like" covering. I had no desire to reassemble this one after the autopsy. Cause of the death: the pentaprism, fixed with the help of a sort of hard cement, got off, and a piece of the hard cement went blocking the cocking mechanism.
