Colt SAA that I picked up in a Seattle WA hock shop while visiting the World's Fair as a kid in 1962. I had about $75 in my pocket and wanted a Peacemaker in the worst way. Found a nickelled black powder .45 in decent shape priced at $84. Got my friends to kick in the balance of the money, fibbed about my age, and it was mine.
It was a renickel job and had a 7 1/2" Christy barrel on it, but mechanically ok and fairly tight. It still had the original black powder barrel so for a while I only loaded BP ammo for it. That got old and I ordered a new Colt cylinder for it; eventually I also put on a new Colt barrel as well. The grips were ugly fake stags. Somewhere I found a block of walnut, improvised a chisel out of an old screwdriver, and went to work making a set of one-piece grips for the gun. Darned if they didn't come out pretty well; the whole package made a nice looking gun when done. An authenticating letter from Colt in those days cost a whole $5; the gun was shipped to Hartley and Graham, a major NYC jobber, in a lot of 50 on April 1, 1882. In turn they were major suppliers all over the US in that time period.
The old buster isn't quite a collector's dream with the changes done to it, but it still looks awfully good for a 130 year old gun. It's retired now but still ready to go shooting at a moment's notice.
