Looking for TRW RF Semiconductor Spec and Motorola 48-869xxx Cross
Went to archive.org. Their copy of a 1970s Motorola databook shows MRF412 as their suggested substitute. Does suggest that the specs in Motorola's data sheet will be close.
I'm pretty sure we had a TRW transistor brochure sort of pamphlet decades ago, but I haven't seen it in ages.
