Has anyone determined what codes represent the thickest socket walls?

Well, I found as many USA made 12 point 11/16" sockets as I could, 3/8" drive, with different markings. Here's what I was able to find. From left to right is circle with H, double line V, single line V, single line VV, single line G, single line EE. You can be the judge, but looks to me the EE has thickest walls. Not sure that means much though considering I have the H series from the 30's-40's that I still use regularly because of the low profile.
I couldn't find an explanation for the single or double line sockets, but here is the list of symbols and what they mean.
H-circle = New Britain, ca. 1931 - 1947
E/EE = National Hand Tools/Stanley Works ca. 1982 - 1991
G = Easco, ca. 1979 - 1989 the Gastonia plant.
G continued = Danaher, ca. 1990 - 2011
V = Moore Drop Forge, ca. 1946 - 1967
V (continued) = Easco, ca. 1968 - 1986
VV = Easco, ca. 1974 - 1989
VV continued = Danaher, ca. 1990 - 2011
Then I found a few other random sockets with different codes (G1, G2, G2D) and 3 of the same ratchets I have with different markings and design.
G1 = Danaher, ca. 2000 - 2004
G2 = Danaher, ca. 2004 - 2008
G2D = Danaher, ca. 2008 - 2011 - This socket also has the laser etching
Hope this helps a little.
