I would recommend Eddie Janice at Peacemaker specialist, Eddie is currently doing work for me and I've been impressed with his responsiveness. Eddie called when he was ready to receive my pistols. One week later he took the time to call and let me know where he was in the process on the work he was doing on the guns. I have never had a gunsmith contact me to give me a status update.
Eddie will tell you he has three types of jobs that he takes in.
Short-term - jobs one week to 30 days, i.e. fitting cylinder, parts replacement.
Midterm - jobs 30 days to six months, which can be any combination of work i.e. gunslinger deluxe action job, Checkering hammer, beveling grip frame, beveling cylinder, re-fluting cylinder, fitting grips, and refinishing.
Long-term - jobs, can take anywhere from 1-2 years for a complete restoration of first generation colt single action Army, especially if it requires re-welding re-cutting and fitting the hammer. He also explained that when he does full restorations likes to have 5 or 6 guns requiring the same process before he starts a restoration project.
Eddie's customer service is great and outstanding work.
