Okay, you both asked very good questions, I can only answer a few 100% positive. Yes the saw is mine, I got it many years ago at an auction not knowing much about it and its been sitting in my shop for a long long time. I have a good amout of old chainsaws and I was going through them and starting them and working on a few and I finally decided to look harder at this one. I cleaned it up and found out it was a disston. I don't really have a desire for a two man pneumatic so I would like to find someone who really appreciates it. As far as a price I have no clue what its worth really haha. And as far as model I'm not 100% on because you will see in the tag it was never stamped from the factory, model or serial number?? Maybe it was close to the first or last on the line?? I did some research and apparently its pretty rare, I only see a video of one other that looked identical that was called a 375, but only found info on two models of disston pneumatics and it says a P-27? The saw is 55" overall and has a 24" cutting surface with the rare disston scratcher chain that's in really great shape. The saw overall looks to be in great shape and complete. Only damage seems to be that one piece is busted that I guess would almost be considered a log dog but its on the backing aide of the bar and not the case so it would be an easy fix to be 100% by undoing a few bolts and putting another on, if you can find one I suppose. I am located in southern New Jersey. If anyone is interested, has any info, an estimated value, or any questions I would appreciate any help thanks Joe
