Royal Air Force Machlett VT-31
This new Royal Air Force VT-31 has an orange U. S. Signal Corps inspection stamp.
"SC7964A" is the code for
the SigC "Inspection Zone"
that checked up on Machlett.
The project that got it built here was the Lend-Lease program - that is, the business of supplying
the Soviets and British with all manner of military supplies
(Spam to tanks), with a not-very-serious notion of some-
day billing them for the stuff.
