john, yea its original. paid 140 on ebay. supposedly it was found in the attic of a homestead in canada by a fellow who worked for the canadian land management or something like that. he had it for 10 years, then sold it to a collector who then had it another 10 years but never ran it. basically all i did was wipe it down good, rinsed the tanks and put fresh mix and oil and it fired right up, tweaked the carb and it runs perfect. when i pulled the muffler,(this is a later model that has what actually resembles a muffler) the top of the piston was still clean. i don't think it had more than 5 hours on it, if that. i have run a 32" gb with oregon round chisel and it pulls it through 24" hard maple easily. currently i got a nos mcC 28" hard nose on it. those are pretty cool old bars. a fun saw to run, for sure.
