Is there documentation for this chronological sequence that I don't know about, guys?
That there are boxes with 5- and 6-knuckle hinges with Walden sets in them is no question. I'm asking if there are catalogs or some other dated documents that show that 5-knuckle boxes were produced earlier than 6-knuckle.
I am very familiar with the concept of dating found sets based on their early or late war midget set specs (specs I de-constructed from RAPD figures and catalogs), finish, and hinge elements, none of which I subscribe to as definitively as I used to without proper provenance. You guys may not know this - because it was before your time on G503.com, it was me who actually first posted a 6-element hinge box with an FSN on the lid and late war and postwar pieces in it (see "General Mechanics Tool Set" thread, page 5, post #7, Saturday, January 21, 2012, 6:25 PM), busting the logic that GMTK pioneers Luca and Roger (Utah, not UK) had been using prior. Instantly, everyone rushed to make the '5-hinge early / 6-hinge late' sequence, and by the time the second wave (Phil, etc, and you guys) arrived, it was codified. But that sequence is regularly busted by sets with all kinds of mixes (finishes, styles) and configurations (types of handles, number of points) with no provenance. It may be no sequence at all, just different box suppliers or different hinge suppliers to the box suppliers. Or it may be a sequence, but just not as 'early' as we all 'want' it to be.
(EDIT: Not trying to dissuade you... but just so we're square, my current position is that Walden may not have provided any 1/4-drive 41-W-2615 spec midget sets to the Ordnance Dept before mid 1944, coincidentally, when they had a proper ratchet. Any sets they produced that year would've been the midwar spec (for brevity, more handles, fewer sockets, incl some 12-pointers). And by the end of the year, the Army had adopted the late war spec. Also, note that in 1941, the catalog shows that they weren't even using side-hinged boxes yet. I strongly suspect the 9/32-drive sets they were making for the Navy (contract awarded 4/1941) came in OD green colored versions of the back-hinged sets they were still using commercially in 1941. (See examples attached - and note, no ratchet.) Their next twelve (12) contracts with the Ordnance Dept were for cartridge holders, fixtures, shot, and machine tool equipment. Their first contract with the Ordnance Dept for anything else was "TOOLS" in April 1943. All the contracts for "SOCKET WRENCHES" came late 1944 and 1945, details above I won't belabor again. Is it possible the "TOOLS" contracts contained midget socket wrench sets? If you want to read it as the ORD suddenly being more specific later, I suppose.)
But, barring the old G503.com thinking, thinking I was part of from the beginning, has there been some new documentation revelation on the boxes that I am badly behind on?
Sorry so long. Coffee buzz.
