I've got a Iver Johnson Model 66, if that will help.
I'm looking for an Iver's Johnson, about 1912, .32 cal., not the hammerless, and it's just the trigger group + the hammer.
I always find .38s or hammerless .32s but never a .32 with a hammer.
I don't even care to ever fire it even if it was safe to do, but it's my great grandfather's pocket pistol so I'd like it to go click when I pull the trigger and have the hammer drop and the cylinder rotate.
