This Chinese production C96 Broomhandle pistol is found in the collection of the UK’s Royal Armouries. Curator Jonathan Ferguson showed it off recently in this video briefly.
It notably the word pistol engraved on the side where it should say Mauser. Just in case you couldn’t tell I suppose.
I recently recreated the C96 in 3D! https://www.artstation.com/artwork/XgrkbD
Not the chinese version in particular but I thought I’d share anyway. Very interesting pistol
