Don't know if it helps or hurts, but here's a quote from Bill Ricca:

From CMPForums, by Bill Ricca:
Stanley Works magazine were not made for Winchester. There were two Ordnance Spare Parts contracts; I have both.
5/44 to 9/44
8/44 to 5/45
Years ago dealers spread the myth that because there was a W on the magazine, it went to Winchester. It made them easier to sell. I do not doubt it may have spread to a published book or two.
