I bought this older worm drive saw yesterday, sight unseen. Going to go pick it up in the next week or so but I’ve been trying to do some research on it in the mean time. Im sure once I have a serial number it will be easier, but for the most part I’m finding info on the older blue label saws, and then the newer saws with the plastic handles, or just new mag 77’s for sale. If anyone has any info on them, or could point me in the right direction I would appreciate it.
