Just a thot for those that might be contemplating the purchase of this pistol, If 1920's vintage it should be safe for smokeless ammo but, of course, have a gunsmith check it first. I've read various sources that ammo is diificult , at best, to find and very expensive when it can be found.
Be aware that Dixie Gun Works sells a brass cartridge insert that enables one to fire a 41 rimfire using 22 rimfire blanks, black powder, and a 41 caliber round ball. Little slow to work but they are fun. I use similar brass cartridge inserts for a 32 rimfire pistol and, yes, it's fun!
Just my 2 cents.
