It looks like 136103 was well cared for during the past 100 years.
I found my M1917, 83163, at a local shop about 15 years ago. At the time I collected some WWI gear. I just generally like S&W revolvers and didn’t have an early hand ejector. My M1917 goes nicely with my 1917 Eddystone, Patton saber, and some of the cavalry saddles and gear I’ve acquired.
My 1917 has seen use and, I think, has been reblued sometime during its life. Some of the proof marks seem to be buffed and I can see some buffing marks behind the recoil shield. However, it still had its original barrel and other serial numbered parts. When I bought it the barrel was heavily leaded. So much so that I wasn’t sure if it was leaded or pitted and rusted. I took the gamble and with cleaner, a lot of elbow grease, and only shooting jacketed bullets I was able to clean up the bore. Now she’ll shoot 1.5 inch groups at 15 yards with .45 auto rim.
