I just bought this Military 1917. I know it is not a "perfect" piece but I want to confirm what I found. Serial # shows it was made in Dec 1917. Cylinder serial # does not match and was made in Mar 1919. Grips are not original for this early variation of the 1917 but the hammer is grooved and the GHS stamp is there. What puzzles me is the barrel. The finish does not match the frame. Barrel is more "blued" while the frame is more "military" finish. There is NO serial number under the extractor but there is an "S" with a small "H". The barrel is stamped "UNITED STATES PROPERTY" and "S&W DA 45". The action is tight and overall the gun is in great shape for its age. I think the barrel was a replacement from existing military stock. Any ideas???
The barrel is a replacement. I don't know anything for sure, but if I had to guess, I would say it was an armory "parts gun". The only very shaky evidence that it was done by a military armorer is this:
-you don't mention any factory service marks on the frame (stars, 3-digit date, etc.)
-if the cylinder had been replaced at the factory, there would almost certainly be a "star" and it certainly would not be marked with the SN from another revolver
-the barrel has certainly been replaced, and since there is no SN, but there is a "star" (looks like a star in the photo) my shaky guess is that it was from replacement stock, which was roll marked as US property by the factory and provided as support to depot-level armorers (etc). I'm almost certain the factory would have stamped the replacement barrel with the SN off the frame and a "star" to indicate the service
-makes some sense to me that the replacement of the barrel and cylinder was done at the same time
-the difference in finish most likely results from harder service before the parts replacement than after
-I don't see any indication of armchair gunsmithing on the barrel...looks like whoever did the replacement had the proper jigs/tools to do the work properly
-looks like the replacements were done fairly early (the cylinder finish close matches the frame...the barrel looks "newer" but has still seen extensive service of some kind)
I would like to know more about how these guns, and the later Victory models, were treated in terms of finish. I have seen many 1917's that were "parkerized", but I don't know if this was done by military armorers or after they reached the civilian market. I have seen lots of Victory models that were obviously parked/re-parked by somebody. I know that the armories/depot level support routinely re-finished 1911's, but I just don't know enough about these revolvers. On your gun, the finish is almost certainly original on the frame, barrel and cylinder, they just have different amounts of wear.
Nice low SN. Correct grooved hammer. Incorrect latter style stocks, as you acknowledged.
