PPSh-41: Misc Internal Parts
Using a cutaway poster as a guide, I built the trigger assembly internal parts and the rear sight.
The rear sight is pretty clever as it uses an inverted "v"-shaped piece of metal as a rocker spring to toggle two different sight apertures.
The trigger parts remain a bit of a mystery as far as their function and relation to each other. Hopefully all will make sense when I ASSEMBLE it.
