[Milsurplus] Tool box ID ??

[J. Forster]

Can anyone help ID a tool box for me ? It came from a recent estate sale.

Physical:  It's a rectangular steel box, 9" high, 10" deep, and 20" long. There
are two latches on the front and part of a hasp for a lock. Inside there are
lips at each end to support a removable tray about 1 1/2" deep with partitioned.
It's painted inside OD wrinkle. The outside has been repainted gray.

Inside the lid, there is a list of contents titled 'Parts & Tool List'. Aside
from a number of lamps and brushes and standard tools, the following items are
listed:

Starting Crank Assy.      K-6720204
Jack   AGK-9
Flexible Exhaust Pipe    M-6730280

Does anyone recognize it?  BTW, among the tools there is what appears to be a
plug wrench for a hex about 1 1/8" AF  and a neat 'S' shaped adjustable wrench.

Thanks,
-John
