Is what I have in my notes from finding a few of those and Turtlefoot’s (a member who used to be on this site and knew nearly everything about shotgun headstamps) website was still online.
Mine are 12ga, yours 16? Hard to read, don’t know if date would change but wouldn’t think so.
Thanks for the replies everyone, I thought it was around there based on searches of this forum, unfortunately the links provided are now dead. RIP to those site and thanks again everyone
