[John Koenig II]

Gentlemen, I am looking for assistance identifying a Parker Brothers SxS Hammer Shotgun. The shotgun has a complete shoulder strap. This is my Great-Grandfather’s gun and I can account for possession all the way back to at least 1957. Based on the Parker Brothers website information, the following are the markings that I have found:

Water Table: Left side “17253” and “MAR 15 1975”
Fore Stock: “17253”
Fore Stock Lock Slide: “17253”
Bottom of Barrel: “M+” and “8479” and “O2”
Top of Barrels: “PARKER BR’S MERIDEN CONN PLAIN TWIST”

I have photos to post as soon as I figure how to attach them. If there are other locations on the gun to look for markings, please pass those along as well.

I look forward to any and all help out there.

Thank you in advance,

John
