I took the rifle apart for cleaning - the stock, except for the RI marking, is quite unremarkable. It's an S stock with grasping grooves; two bolts & is cut for the spare parts container. It has a few gouges, is missing a small chip on one side & is worn around the toe. Is is not split or cracked. I rate it as good condition. The handguard has a 5" crack at the front. It has a convex profile, circular windage know cut out and has a fixturing slot.
A strong concentration of Simple Green removed about 80% of the grime on the stock. The metal was in pretty grim condition, too. I don't believe it has been cleaned for several decades. It still needs work.
