I have a few of these, 6.5 n 7.7 The last ditch rifle is interesting. I have one too.t Sharp receiver rails, wood butt plate, fixed rear sight n simplified front sight w/o guards. Yours probably still has receiver cover grooves. The rifling is polygon and and will shoot well altho looks worn out. If the bolt serial number matches the receiver its probably safe to fire but safer to put butt in tire, tie long string to trigger, crouch down n yank string. If case is not bulged. Its probably ok. Ammo- check with Graft n Sons for non norma ammo. Stock has orange tint shellac n is hard to duplicate. Matching numbers? Mel
