deyomatic is right, it appears all correct for 1917 Army Model, with US butt markings removed neatly, not a commercial model. The com'l models have a serial # parallel to the butt like all other com'l models except those stamped on the front grip strap, 90 degrees from the one pictured in my post #2. But com'l models very often did have lanyard swivels.
My notes on 1917s:
1917 PRODUCTION SUMMARY:
Military 1917s are in the range #1 thru # 169959 which were completed in 1918. As usual with S&W, not all numbers were used. All were shipped to Springfield Armory.
If there’s an extra large stamped # like "19567" in the yoke, it’s an arsenal # indicating they reblued/refinished the gun.
Most early WWI 1917s are marked "GHS" in a circle, (Gilbert H. Stewart, Gov’t inspector), left side frame up near the hammer serial number range 1-42000. Middle range guns are marked with a flaming bomb, beginning c. #42000, April 1918.
War time 1917s did not have S&W trademark logos.
Earliest have smooth, concave top stocks and circular hammer grooves up to about #15,000. Although, many have been observed sporadically up to the #20,000 range. As with all things S&W, there is seldom a specific serial number cut off. Stocks w/concave top and the hammer grooves were deleted 1st.
Late war time guns are marked in various locations with an eagle head and "S" followed by a number like S1,S2, S3, S4, S6, S9, S24, S27, and S34, from April 1918 to war’s end or serial number 169959.
These marks are inspector marks used on Military guns which are also marked "United States Property” on the underside of the barrel.
The butt of the gun will have a two line serial number (when over 3 digits) and U.S. Army Model 1917 in four lines as well as a lanyard ring. “UNITED STATES PROPERTY” is roll stamped under the front end of the barrel.
Serial numbering of 1917s, Smith vs. Colt:
Many do not know that S&W 1917s are #d differently from Colt 1917s.
Smith also uses the serial # on the butt for the required government # as well.
Colt put the government # on the butt and its serial # on the frame in the crane.
The S&W serial # on the butt, as opposed to Colt, served a dual purpose; it was also S&W's government #. The serial number on the COLT US Army Model of 1917 is stamped on the frame, behind the crane, and a different number on the butt of their 1917 is the government #.
