Gunsmithing (no politics)
Akima:
Reading the Chinese characters ( 刑事警察局 or Criminal Investigation Bureau) on the sheets, and looking at the logo printed underneath (which includes the badge of the Taiwanese National Police Agency, I think that photograph was taken in Taiwan, not the PRC. I remember reading that a man had been arrested there some time ago (2005?), I think, for running an "underground arsenal" making those things for criminal gangs. I recall the reports saying that the cylinder was rotated by hand, and the "pump action" simply served to cock the hammer.
GarandMarine:
Crude. But effective.
Caspian Sea Monster:
Adding a pump slide to recock the hammer/striker (can't tell which it is) seems like a grossly inefficient use of shop time and materials when you still have to rotate the cylinder by hand.
Grognard:
agreed.
I think the recoil would be VICIOUS with any shot over 20 ga.
Akima:
What is the difference between a hammer and a striker?
As for the "pump action", I am guessing it is rational from a safety/ergonomic point of view. I don't think you'd want to carry something like that around cocked, since I'm sure it has no sort of safety-catch. Without the pump thing, the firer would have to take a hand off the pistol-grip or fore-grip, of a rather unbalanced weapon, to pull back the hammer/striker. With the pump, the firer would be able to keep both hands in their proper position while readying the gun to fire. It does seem odd though that the maker didn't include some kind of stud-and-cam type arrangement, having already done a substantial part of the work, but perhaps that required more sophisticated machining than he was equipped to do.
I googled "cam stud operated revolver", and found this. Of course, as an avid fan of the Ghost In The Shell universe, I was aware of semi-automatic revolvers since Togusa carries one in the manga and anime, but this looks like something straight out of a steampunk comic.
