Does anyone have a datasheet, or any technical information at all
(frequency, power and nominal supply voltage would be adequate for my
needs I think), on this obsolete TRW transistor ?

Steve,

I am almost positive that this transistor (PT4370C) was used in the
Transworld RF amplifiers.
There is a Motorola MRF equivalent.
RF Parts will either have the parts or a Motorola cross reference.

If you post this question on QRZ Q&A, one of the regulars use to work at TRW
during that era - likely has the old spec sheets and any history you may
want.
