NICE! Are you planning to shoot it? Are you going to put it in a holster? Even with a cowhide-lined holster, there is bound to be some bluing wear at the 7-9 places where the gun must contact the inside of the rig.
(First holster and belt rig I ever made for someone other than my self was for my section OIC in the Air Force...for his 2nd Gen Colt's buntline. Last time I talked with him (3 years ago), he was still using it!
