Hello SSS,
I'm looking for information on my Spencer Rifle # 3780.
Two Flints, thank you for the unit issue information. Thanks also for posting the photos I sent you.
One of the photos shows what the seller of the gun thought was an inspector's mark (I zoomed in to show it better) which appears to be "AP" or maybe "AD". Do you think he is right? If so, is it a common mark?
Thanks again.
