Chicago Firearms Co. "Protector Palm Pistol", squeezer action. .32 cal extra short rimfire. Rotary "magazine" held rounds pointed out in a circle. Most were nickle plated and blued guns are scarce and desirable.
Minneapolis Firearms Co made one even smaller in .32 centerfire. More scarce than the Chicago.
I've seen a few, but never saw one in working condition. Seems they were fragile and persnickety.
Both held seven rounds I think.
