[R-390] 1968 EAC 390A

[Tom M.]

There are so many problems with your post I don't know where to start.

First of all the tooling was owned by EAC, not the Govt.  This was not a govt
ammunition plant.  It was a private business.

EAC built the units sold as commercial units by EAC.

Collins did not make a small proof of production batch of R-390As, they made
about 6000 units or more than 10%.
