Yes, they were very common around the turn of the century. I have 6 of the little buggers, 3 in .38, and 3 in .32. In this snapshot, the hammerless is a US Firearms, and the hammered revolver is an H&R. The US Firearms revolver has no marks or corrosion that would suggest that it has been fired. The H&R has been fired but has been well taken care of and is very clean. These are used quite often in cowboy action shoots.
The worst part is ammo, ooooooeeeee,,about $35 a box.
