That's good, always nice when you get your hands on a mechanically sound antique, looks like the previous owners all decided to take good care of her, lucky you!.
One of these days I'm going to get myself a pin fire as well, they are still affordable and HC collections in France supplies everything for reloading these guys.
Careful, your going to be hooked now, it never stops after that.
One other thing, any proof marks on the cylinder faces anywhere or on the side of the frame?
