I've got a remington Model 1858 that was used int eh Civil War. Not sure if it's exact DOB, but obviously before 1865.
Also have a funny trio, I've got a Winchester 74, semi-auto .22 Rifle, a S&W K-22 and a Colt Woodsman, all made in 1947! I've got other, older ones and have owned many other pre-WWI guns, but few remain today.
Webly MK-IV from 1917. A S&W pre 10 from 1936. Both are still fine shooters. Ohya, the Remington 341P rifle that was my Dad's that I learned on from 1938. Then comes the M44 Moisen and the Lend-Lease Enfield by Savage. Well that brings us up to WW2 and modern stuff.
