does anybody recognize these transistor manufacturers?

I have 2 2N2369 transistors that i'm trying to find the manufacturer/brand.

I attached a picture of one of them. I can't make out the logo. Along the side, it says 2N2369 7326S (the 7 is hard to make out so it may not be a 7)
The other one has no logo but the side says 2N2369A 739 AA

they both are metal cans and both have gold leads

National Semiconductor; that is their original logo.

The "7326" is the manufacturing date; 26th week of 1973.

Just for info, the "A" suffix one [usually a gain-graded version] is still available from some suppliers, though not manufactured for some years.
That will also replace the non A type.
