Just an interest thing ... I know several folks have some real old firearms, in fact IIRC Betty inherited one this year.
So - what is your oldest - not in type but actual manufacture?
I think my oldest is probably a Webley MkVI altho I have two crappy old revo's which must be pretty ancient - a "Young Americans" in .22 short and an Ivor Johnson in .32 S&W. I also have a Mauser Obendorfe bolt rifle in .22 which research suggests goes back to the 20's (wish I could find a spare mag for it!).
Several other guns go back to 50's and 60's but not early 1900's. I guess those of us with early milsurps can count those in too - but thinking more of non mil.
What have you got that's real old? Pic's are good. Here's my Webley and Mauser .....
