Found this 1928 Snap-on #2513 Buick cylinder head stud bolt wrench Sunday.
The pics show the initial condition of smooth rust, which I removed with a screwdriver and a wire brush, then the cleaned-up condition, and close-ups, including two of the 1928 date code, stamped midway along the shaft, opposite the Snap-on logo. The 1927 version of this tool (#2511) is shown in catalog with two box ends, but the 1928 and later versions have an open and a box end. I thought it was interesting that the part number begins with three very linear sans-serif numerals, but ends with an old-style serif numeral. It looks to me like the "3" is stamped over a "1", or that the "2513" stamp itself was modified from a "2511" stamp.
Also in the box were two S-9585 axle shaft drivers, which I handled, but did not recognize, and did not purchase. They did not appear to have any markings on them, and I identified them only while looking through pdf catalog from 1932 (p45). The place is mostly furniture, and I'm skeptical of returning before the vendor tosses them (it's a two-hour drive).
Thoughts on the rarity, importance, or desirability of these drivers?
