Thanks for all the information, guys. Sounds like my Nitro Special guess was a good one.

Walt, I will get you the SN when I can, and appreciate that help.

Going from memory, the gun definitely has double triggers, a checkered stock and double ivory beads. Haven't measured the chokes or chambers (probably short?), but the bores are in real nice shape. I'm thinking it does not have ejectors. There's a decaying pad (factory?) with a well-known brand name I can't recall. TT
