What I have is an S&W .38 spl revolver with a 6" bbl, fixed sights and a serial number starting with C 28xxx. I bought it used back in the 80's from a friend who owned a small sporting goods store in Santa Clara, CA. It has an L on the yoke cutout above the assembly numbers. I don't seem to be able to find any info on that letter. I remember sometime in the 90's I contacted someone from S&W by email and got info on the serial number, but that computer crashed before I had the presence of mind to print it. All I think I remember was it was a NYPD issue. I thought the email stated it was from 1935, but when I checked the serial online it seems to be more like 1953. It has holster wear and also looks like someone tried to file the trigger guard off with little success. If someone has any info on the letter and/or any other info on the revolver I'd really appreciate it. I love the gun, it's a good shooter and I'd never sell it.
