I am trying to figure out what caliber and model Bell's Mauser pistol (AKA: Bom Bom) was... In "Bell of Africa" he writes, "...a Mauser pistol which could be used as a carbine.." Have been thinking he was probably using a Mauser Model 1896 "Broomhandle" with a detachable stock. Can anyone confirm? Also have been looking through my library but can't find a reference to a cartridge or caliber for it. Does anyone know? Was it written in one of his books? If so, where? Any help appreciated.
