I recently purchased this saw at an antique store. Its a small panel saw with a 12” blade. I grabbed it because I hadn’t seen any other Disston’s like it before and I was intrigued. I haven’t been able to find any others like it online and I was hoping someone could help me identify it. I know that the Keystone series was a budget saw line from Disston but I am wondering if this saw would be a good user worth keeping around.
