3mm (.12 ins) "FURR" Pistol

Recently found a cartridge intended for a miniature or “watch-fob” pistol. It is centerfire, has a rimmed brass case and primer, lead round-nosed bullet. Bullet diameter 3mm, case length 7.5mm. It was labeled “Furr pistol” and is very well made. (no I didn’t pull it and I’m not going to section it).

I’ve been through my records and cannot find reference to it or the term “Furr” - either as the caliber name of the maker of miniature pistols, but it sounds familiar !! Anyone have any information??

I know Furr as the manufacturer of several miniature versions of the Gatling gun, but I don’t know if this is the same “Furr”.
