None of that would help with in-house numbers, which are exclusive to the company that orders them.I recall at NSC there were published lists for transistor markings, and markings for
special screened transistors. Motorola used to do a lot of this. as well. In my library I looked
at 1970 Fairchild Transistor data book, no luck thou.

No, thats not the case at all. They were used both for specific customer and for special screens
for broader customer base.
Not really 'in house' then
