Kicking around some antique shops today with my wife and scored. Picked up an 18" backsaw with a steel spine, 3 flush screws with split nuts and no medallion. Spine is stamped Disston and Toland. From what little info I could find online it's a very rare stamp that dates to 1843-1845 and precedes Henry's founding of his own venture.
Sorry, I have to wait till tomorrow to post pics. Staying in a hotel this evening and the saw is in the trunk.
Anyone ever seen such a stamp? Any other info floating around out there? You out there, Pete?
