Honestly I think it is a mix-n-match from the previous owner. Nothing fits a given model. It has the straight stock, which by all means looks to be a authentic Marlin stock and not a reproduction from another company. It also has a saddle ring and the gold trigger. The other thing funny is that it has the square lever. It dates to 1982 or 83, don't remember. I haven't been able to find those options together in that year in any reference, though it may be possible I haven't found the right reference. Something leads me to believe that someone has decided to add their favorite parts to this rifle long before it saw my hands. It was an auction buy so I don't have any previous knowledge of what it was beyond what you can see.benzy is that a 336rc? the staright gripped models are rare, i have a 1967 rc.
