I cajoled a friend of ours into sending me a picture of his Colt New Service, a .455 rechambered to .45 Colt. Bought it in patina condition in 1975 and then in about 1978 had S&W sights and ramp front added by Richard Heinie, who was then the local guy who would do about anything.
Stocks in the Farrant-Hurst-Stark-Blackford style are by another local guy.
Additional info from the owner: The serial number is in the 83100's and according to Sutherland, it was manufactured in 1915.
