I have a late 3rd Generation Colt Sheriff model, black powder frame, 45 Colt, in excellent condition. It comes with the original custom shop box and all the stuff that was/is in it. White sleeve is present, but bunged up. It has had perhaps 25 rounds through it. As you can see from the attached pictures, the case colors are bright and vibrant. I wish I could say the same about myself.
I'm looking for a Colt SAA in 44-40. I prefer a 4 3/4", but 5 1/2" is ok. I would hope that your trade is in pretty good condition too.
If you have a pair that you would rather not break up, I'm willing to add some of my safe queens to the mix. They aren't Colt SAA's, but they are pretty nice. One is a Colt Signature 1860 Army (44 caliber, of course). These are considered, by some, to be 3rd generation black powder Colts. But, that's a matter of contention. It has never been shot, however, I did have Tom Sargis at Bozeman Trail Arms (www.bozemantrailarms.com) do an action job on as I planned to, but never did, shoot black powder. No box with this one. Next is a 1860 Richards-Mason Conversion in 45 Colt. (Uberti) Last, a 1871 Flat Top. (Uberti), also in 45 Colt. Those both come with boxes, etc, but have been shot once.
If you're interested, send me a PM and we can talk via the telephone. Also, I can send more pictures if you need them.
Best regards, and thanks for looking.
