I've had the spiral push screwdrivers for years. Usually use them instead of screw gun, or anything with a tail on it. Have some of the large Yankees 120s, and the 131As, Stanley as well as the original Yankees. Found a NOS Millers Falls at an auction, still in the box, pack of bits unopened. But the other day, I found one in a pawn shop. Older maybe, wood grip, has a collet type holder, with the name George Gay Combination No.1, pat. 1892. Has forward, lock, and reverse, and no spring assist on the spiral. Is nickel plated. Just a bit out of the ordinary in looks, I wonder how many different companies made these over the years?
