Hasn't been a post on the WW2 "GMTK" sets in a while..
An interesting thing about the "Stevens-Walden" boxes is that they come in two variations
(three if you want to count the stock # marked boxes), the major differences in the two boxes are the hinges, all the stock # marked boxes I have seen have five "barrel" hinges while the plain non-# marked boxes have six hinge "barrels".
At first thought it would clearly indicate a reason the five bar hinged boxes would be in favor for a WW2 set thanks to the association of the stock # found on some examples, but some six bar hinged boxes have apparently turned up in surplus (
). So both were used, seemingly at some point around the 1940's.
And of the #'d boxes the tool finishes vary..
Please check the hinges on your #'d boxes, five or six barrels on the hinge?
An update, Wingnutt posted an example of the other box with the 6 hinge barrels that had the stock number on the lid.
