I was recently given an old (not sure how old but at least 45 yo) and non-functioning Springfield 187H semi-auto .22 rifle (tube feed). I was able to find an exploded diagram and was able to disassemble it just enough to figure out that the firing pin is broken.
During my web search I could not find a manual for this rifle.
Does anyone know where I can get a manual with disassembly/reassembly procedures? I'd like to tear it down, clean it up, replace the pin (Numrich has them), and see how it fires but there are a LOT of small parts and I'd like to have some idea what I'm doing before I take it apart.
TIA for any help.
