Help ID - Early Craftsman Open End Wrenches

[OilyRascal]

I have another quest to identify what I believe may be a treasure in my toolbox. I have a set? (4 wrenches) of open ended Craftsman wrenches as follows:

3/4 & 7/8 wrench with marking "Craftsman No.4" (note the craftsman logo is not underlined).
5/8 & 11/16 wrench with marking "Craftsman No.3"
1/2 & 9/16 wrench with marking "Craftsman No.2"
3/8 & 7/16 wrench with marking "Craftsman No.1"

They all have has markings "Forged in the USA" and a series marking of -V-
on opposite ends of the "No." marking. The reverse side has only the size on each end. There are NO markings on the shanks of any of the wrenches. I believe (based on Craftsman Gold sockets with logo's by year) the logo was introduced in 1940, and ended 1970.

The alloy artifacts site notes a "rare" -V- series set of wrenches that are identical, with the exception of the Craftsman logo NOT being underlined on the wrenches I have. They refer to them as a "tappet" wrench, and note it (the No.1 3/8 & 7/16 combo) appeared first in the late 40's.

Does anybody have an advise on how to best narrow the date of this toolset? Thanks in advance!

I've always heard of those as "tappet" wrenches - and that is how they were originally described by Sears - but for a while (late 40s through 1957) they were marketed as "check nut" wrenches.

Your set appears to be from 1959 or later, and they still appear in 1972-3, which is the last Craftsman catalogue I have...
