I own a .22 short/long/long rifle (semi-auto in LR) marked as a "Springfield Model 87A - J. Stevens Arms Company - Chicopee Falls, Mass. USA". It has four patent numbers on it but no serial number. It is a rather slim rifle with a tube magazine and small, lockable bolt knob. Since it was my Grandfather's rifle and the first firearm I ever shot (at age seven), it has great meaning to me and I really would like to restore the gun. I also remember it being very accurate and I personally dispatched many groundhogs and rabbits with it as I grew up. I really need some reliable information about the piece and locate some parts for it. The pot-metal trigger guard crumbled away almost 25 years ago and the old plastic butt-plate cracked in half way before that! All of the original blued finish is long gone and the wood of the stock is in dire need of sanding and refinishing. I want it to be a shooting, working firearm again, something I can pass down to my Grandchildren with pride after I get finished enjoying it again. Does anyone have any assistance for me in this quest?
