Hello. I just found a little spring lying on the floor near where I clean my guns and I want to say it came from my Model 1913 .35 auto, but I want to make sure. Can anyone upload a nice clear scan from an old S&W parts catalog that shows the Model 1913 parts? The spring in question is a little spring, probably about 1/2" I think might be the extractor spring. Does this gun even use an extractor spring? First, is my extractor that little funny-shaped rectangle with the tab on the back that goes into the oval-shaped cutout in the breech block? See my problem? I have no idea what I'm looking at. I put the spring into the cutout for the extractor (if that's what the rectangle is), and it seems to work in there, but I don't know if I'm just adding parts or what. Please help!
