I'm interested in the same info...
The first Craftsman "series" seems to have been C, and they appear to have run from the late 20s through the mid-to-late 30s.
You're right that the BE and H series tools were concurrent. The BEs may have been slightly earlier than the Hs... This theory is supported by the type of Craftsman logo on the tools; the underlined-C logo is present on all BE tools, while the H tools have either the underlined-C logo or the newer double-line logo. These two series ran from roughly 1934-47.
The 1947 catalogue shows both the older New Britain-manufactured BE and H series
as well as the new model line by Moore Drop Forging Co. that would become the V series.
I, too, have a recently-acquired vintage 1/4" ratchet set. Like you, my ratchet has no "series" marking (just the newish double-line logo), but the sockets in the set are all marked "V". I believe it is from the late 1940s since the sockets are also cold-broached! I have perused a PDF 1949 Mechanics Tools catalogue and my set appears therein; the ratchet looks like mine, but the sockets don't
appear to be cold-broached, leading me to believe my set is from 1945-48.
The next catalogue year I have been able to find is 1954. By then, the ratchet is different and so is the box!
Moore Drop Forging Co. was acquired by Easco in 1968. Therefore, I would expect the V series (V, VV, and V-with-a-small-upside-down-V?) to have run from roughly 1945-68, when it would have been replaced by the E-series (which you didn't mention).
It was around this time too that the tools started being marked with part numbers. Does anyone have a V-series tool marked with a part number too? I don't know if such a thing exists, but if so, it's a later V-series.
Easco was bought by Danaher in 1990. Therefore I assume the Es and EEs ran from 1968-90 or thereabouts. E = "Easco"?
The Gs are the most recent (and current) series, and the "G" may stand for the Danaher plant in Gastonia, North Carolina.
Interesting!
