I'v got a JC Higgins 103.229 (Sears Model 229) .22 cal. for Xmas in 1959. Most people say it's a Marlin 81. Took out of storage and some itlems are rusted and am replacing. Spent days looking at different website and seems not to be clear on difference between the Model 81 and the 881. Mine is a tube feed (shots, long, and long rifle). I've attached 3 of the 6 page original brochure. I've located the parts at numeric (gunpartscorp.com) but not sure wheather I need to order parts for Model 81 or 881.
