Would anyone have either vintage TI semiconductor data from the mid-1960's, or a cross-reference handbook, that identifies two pnp germanium TO5 metal can bjt's with TI part # 650859-3 and 651236 ?

Those bjt's are in a Wurlitzer organ reverb module from circa 1965.  All the transistors are fine - I am just trying to locate data for them, as they don't have a Jedec part id.  The NTE cross-reference app only associates both those transistors with their NTE-102 part.  No googling so far has shown up any relevant reference to those part #s used in other equipment, or in cross-references, and I don't have hardcopies any more of the semiconductor reference lookups.

Ciao, Tim

FWIW, this databook is from 1972:

I suspect that your parts are custom orders.

Thanx - yeh I just deciphered a fuzzy part of a Wurlitzer schematic that indicates they were Wurlitzer part numbers - so that covers my request.   :-+
