So, I settled on D-I sockets and have gone from there. Getting close now, only a few sockets left to find; 1/2, 1-1/16, 1-1/8.
The 1-1/16” and 1-1/8” D-I sockets are the hardest to find.
What him say!

But these...
...as you well know, went up to 1-1/8"!
The interesting trick, for general readers, is that the GMTK sets only went up to 1" through September 1942, based on the Office of the Quartermaster General (OQMG) Interwar specs. In October 1942, with responsibility for tracked and wheeled vehicles having been moved to the Ordnance Dept just two months earlier, the 1-1/6" and 1-1/8" sockets were added. This is just one small seemingly innocuous example illustrating the reason for the transfer - QMC's slow and ineffectual response to the war and modernizing their thinking, processes, and material.
Regardless of the brand, many boxes will only fit twelve (12) sockets from 7/16" to 1" in the compartment due to the prewar spec.
I'd have to check the cats (or just ask 4/c! HAHA), but empirically, I know that Duro-Chrome made 1/2-drive sockets up to a whopping 1-1/4" and up to 1-3/16" in "-D-I-".
Beemer, If you get desperate finding the missing sizes on your own, or even if you'd just rather not wait, I do have a couple extra 1-1/8" in my stash.
I don't have an extra 1/2", sorry to say. One of these is from the GMTK, and the other is for a second set I am building. Note that the three or four smaller sizes came in two styles, tapered (a little earlier, I reckon) and straight wall. I see you've got a tapered 7/16", which is probably appropriate for that box, and you'll probably want a tapered 1/2".
