Scored most of a SK 1/4" set over the weekend, in a user made box. (IT appears the box was a larger box, cut down and salvaging the corners. Kinda funny. At first I thought the veneer was coming apart) The set looks to be a 4098, from around 1953, because they went to all 6 pt after 1949. Got the following pieces:
40906, 40907, 40908, 40909, 40910, 40912, 40914, 40916, 40961, 40962, 40970, 40990 (3/16 - 7/16), plus and extra 1/2. missing 11/32, and missing all three 8 pt sockets and the flex handle and cross bar., but my notes say I have an 11/32, the 5/16 8pt, and a flex handle.
It also came with a set of 1/4" drive deeps, which I have not found a set for yet. (1/4 - 1/2" 41908 - 41916), and a universal 40990
Except for the 12 pts being wrong, it will pair nicely with my
4503W and
convert it to a 4502W. Guess I never posted the 4503W here, will fix that soon.
