Albeit late, I'm excited to finally be able to contribute SOMETHING (minor) to this board!

I have an A.J. Aubrey hammerless, 12 guage, Ser. #26941.
Marked on rib "DAMASCUS STEEL MFG. BY THE MERIDEN FIRE ARMS CO. MERIDEN, CT. U.S.A. PAT'D JY. 9, 1907"

"52" is stamped on right receiver flat.
"D32" is stamped on left receiver flat.
31.375" bbls, choked atleast full and full (only had a dime)

Sorry so late, I hope somebody is still interested in the info.
