IMHO you have some very nice pieces in the stock & handgaurd. The others have addressed the handgaurd but I think your stock may be a sleeper. It is a transition period long (4.15") barrel channel M1icon stock. I think Riesch refers to it as a late Type III low wood stock that Inland made starting in the 6 million serial number range, just before they started producing the M2 cut (full auto) Type IV stocks. You don't see these long channel M1 (not M2 cut) stocks very often and yours doesn't look like it has been sanded or otherwise molested to any degeree at all. I think it would clean up really, really nice and have excellent market value. I would baby it (no shooting or car trunks) if it were mine. Interesting carbine. Thanks for the many pics.
