I appreciate your guidance in helping me figure out how to value the Model 23s described in another thread. While we were going through my dad's safe, we found two shotguns we can't identify. Gun 2, below, (with two hammers) belonged to my grandfather. My guess is that it was built in the 20's, but I really have no idea. My grandfather was not a wealthy man, so I doubt if the gun had much value back then and probably doesn't now, but we are taking it to a dealer to get appraised. At this point, I'm just really curious what it is. I don't know anything about gun 1.
Here are some pictures:
First, gun 1:



Gun 2:


Note that the third picture of gun 1 also includes gun 2, and the second picture of gun 2 includes an Ithaca Model 37. There appear to be identfying marks of some kind on gun 1, but not gun 2.
Thanks for any help!
