Hey, thanks! I figured there was an online place to look that up, but I googled until my mouse finger hurt.
My Dad was born in 1938, and I knew he got this as an early teenager. His father bought it for him new at a gun shop in Bay City, Tx that was run by 4 brothers. My Grandfather was going to buy a double-barreled gun, but they somehow convinced him to pay twice as much to get the .410 pump. When I was a teenager (about 1987), my father and I went by that same store and bought some .410 shells for it. There were 2 brothers left by then, and one of them was in the store. My dad told him who he was (small town, and all the old guys knew each other), and that we were shooting the shotgun that was bought there for him more than 30 years prior when he was a kid. The old man cracked a smile that I remember to this day. Dad passed on in 1990, so the old shotgun and I carry on.
