Picked up a 100+ year old Case knife. It looks like a slim trapper but the stamp reads"R2049". The 9 could be a poorly struck 8. The celluloid scales are both cracked. The Spey blade is broke off at the choil. Question is, should I repair it to use, or just save it. The long slim clip blade has some rust on it, but it's usable. The scales could be glued? I really like the size and style of this knife. The factory doesn't have any parts for this neat old guy. What do you think?
