[R-390] Chinese parts

[Shoppa, Tim]

Maybe I'm understanding the numbers on JAN tube boxes wrong.

I thought that somewhere in that code, probably between some hyphens, was the code for the supplier.

Maybe the numbers on JAN tube boxes is different, or a superset of, the NSN?

Tim,

As for the berets, the NSN came from the supply system, assigned for
that particular size and the NSN came as a US sourced item, even though
it was made off-shore.

As for the tubes and a particular NSN being assigned to a specific 
manufacturer,
I really don't know, as when we were still ordering smaller tubes, we'd 
order
by NSN and get whatever the supply system had.

On the other hand, when I was ordering film for my Reserve unit, I could
come up with an NSN for a particular type of Kodak film and we always
got the Kodak brand.  Never got any other brand of film which would have
been essentially the same.

I don't recall if we could specify a brand of say, transistors, ICs or 
coaxial
cable connectors via the NSN.  The biggest problem is making sure the
supply system didn't substitute more expensive hardened IC chips for the
more consumer grade and bill us for the more expensive parts.

That cost a lot of money.
