With Hoss' epic Sachs-Dolmar 166 quest in full swing, I ask this question; What is the hardest saw to find? I would guess the 166 is right up there, but I would assume that pre-WWII saws are difficult to find as well. The Jonsereds 66E also comes to mind because of it's low volume and frequent rebuilds into 70E's. So what do you think?
