Question about Smith .45 acp model 1917
I picked up a Smith model of 1917 in .45 acp over the weekend. In addition to the serial number stamped under the barrel is an S and a diamond. I read over on the Smith forum that the S indicated it had been back to the service department and that the diamond indicated a part had been replaced. I couldn't find reference to that anywhere else however and was hoping someone here would know. I'm pretty sure it's been refinished, maybe by the factory as there is a date, 11/51 stamped under the left grip panel. The pictures aren't very good, but here are a few anyway.
