Looking for more assistance. I'm not being lazy, I'm just not finding the data I need. I believe my clues to establishing a production date for this box include:
1) the metal tag sporting the logo, company name, etc. (versus a paper tag or sticker)
2) the diamond shape of the tag
3) "Sherman-Klove" being present on the metal tag
4) the metal tag being riveted to dead center of the outside front of box (versus to the outside right, inside, or on the lid)
5) the handle on the box being metal (versus leather or wrapped in leather)
6) knurling on the base of the sockets
7) 19/32" and 25/32" sockets present in the set
8) the construct of stampings on the sockets -xxxxx .S-K. Size (where xxxxx is the model number and Size is the actual size of the socket). Note the two dots on either side of the "S-K" are elevated to a vertical midpoint that is center with the S-K text. Also note the lack of "S-K Chrome" stamping. This suggest post 1944 per catalog research.
9) patent number 2232477 stamped on the 1/2" drive ratchet (filed 1939, granted 1941)
10) the 1/2" drive ratchet patented 2232477 lacking a flat forged handle (it is round shank).
11) the finish of the tools being Chrome
12) has recessed grooves on the socket drive end helping sockets stay on drive tool (pre 1955?? can't confirm)
13) all of the sockets being double broached (12-Point)....more notably the 7/16", 1/2", and 9/16" are not 6-point as would be the case starting in 1958 (according to catalog reference).
14) set no. 4205-W with a $29.34 Retail price
15) lack of S-K Wayne stampings on a base knurled socket - suggest pre 1964
16) tapered walls on working end of the sockets
Conclusions so far (please keep me honest where needed): After 1941 because of #9 clue, post 1945 due to #8, pre 1964 per #15, pre 1958 per #13, pre 1955 per #12 clue.
That would leave me at somewhere between 1946 and 1954. Again - looking for any assistance that may be provided.....in particular any S-K catalog references between 1946-1954.
