Well done on getting those. High five to dad as well! The lathing and hammering on that 22 got my attention. I'm gonna guess trans stamp on that one. I have some late 50's with extensive hammering like that. But usually see it more on trans stamps and some large stamps. The patina on the other two seem to look like they have all been together for a while. So that should be a good sign as well. Can't wait to find out what they are.
