Need help with the production date of a Model 10-5
Recently purchased a Model 10-5 at a local store/range. I'm really loving it so far but I'm curious about what year it was made in. I've got a general range of 60's to 70's but wanted to get more specific. The serial # on the butt reads "D7294XX" if I need to post more information about it I can. Here's a few pictures of it and thank you in advance!
