Met with the seller today. Young kid, said he bought the saw from his boss he worked for before starting his own tree service company. Says he was getting out of the business to join the coast guard and needed to unload quick due to going to MEPS soon. Didn't get a bad vibe from him, seemed honest and forthcoming with info. Saw had no previous company markings on it, only a sticker from the dealer he bought it from.
As for the saw, well it definitely needs a good cleaning and some work. Top cover was cracked, rear handle also, sprocket was junk. I only had a little bit of time to look at it, and it was covered in sawdust. Where it gets interesting is what he said when I asked what he thought was wrong it, his answer, "I stripped the spark plug threads". And sure enough, they're definitely stripped. But I was still curious about the state of the piston, took some pictures.
