Yet another 1887 Parker hammer. This one is not a museum piece either. Twist steel, 1 frame.
The fellow I got it from is a member here. He used it to take a nice turkey last Spring.
These guns are quite well-made (even in the entry level grades) & are uniquely American tools, to be used in the art of "shooting flying" (or even for home defense, I suppose).
I prefer the former.
