I have never tried to characterize my M1 before; just shot it. Now, I would like to check it out. Is there an internet source that will tell me which parts are marked and where and by which mfgr? How do I tell if the buttplate screws are long or short? Windage knob is marked 8ME, elevation is WC5. Bullet guide could be either S 98 or S 86.
Will someone teach me to speak 'M1'?
