There's a pile of information out there on these 41-B-1640 boxes. They seen to have been made by several manufacturers, Kennedy and Simonsen being the most common, and they are mostly associated with USAAC, USAAF, USAF, USN, and NAF ( Naval Air Force ).
They do not appear to have been in common service with the US Army for whatever reason. I have several, and they are really heavy even when empty, to the point that a single lift handle must have been useless when loaded.
The G503 Tool Section is loaded with information and examples:

I would normally expect an example with embossed USN to be post WW2, but the socket tray lid layout of your find is definitely WW2 type ( pre-WW2 the top trays were empty, even blank, with no lids or dividers, during WW2 they normally had socket dividers and one side had a lid, some time post-WW2 both of the top section got lids, though probably different manufacturers changes at different times )
It may be worth stripping or sanding the black paint to check for original stencilling.
