Thanks for sharing your Model 100 story. I'll be doing exactly the same with mine by passing it down to my son. Curious as to whether you know if either or both of yours have had their firing pin replaced, per Winchester's recall, due to instances of breakage with the original pins? If not, you can contact Winchester via their 800#, give them your serial numbers, and they will tell you if they have or haven't. If not, they will send you new pin(s). Replaced mine about 5 years ago and my only cost was postage to send them the old pin. Got a brand new pin plus a check for $30 to cover cost of replacement!
