I bought this Colt M1917 (made in 1919) in 2016. The "bolt" was worn, allowing the cylinder to coast past where it was supposed to stop. I finally found a new production replacement and had my gun smith (https://acgwllc.com/) install it. As always, Ryan did great work. I loaded those rounds in 2016 too and hopefully will get to test everything in the next few weeks.
While I was at the gun smith another customer came in to show Ryan some guns he'd picked up. First was a Webley-Fosbery semi-automatic revolver from the early 1900s. What a neat mechanism!! Next was a LeMat revolver from the 1860s. JEB Stuart carried one like it. Finally, although not an old gun, he showed us a custom 1911 Altamont "Dino". Heavily engraved with a dinosaur theme. Beautiful! You can google it to find photos.
