[Collins] 32MS-1A Four channel transceiver

[Cliff Miller]

Just saw a 32MS-1A for sale out of an estate and would like to inquire what
people know of these.  Googling found relatively little information,
particularly no manual or schematic.
>From the photographs, I cannot tell if crystals are included.
The tunable final output tank modules - I assume these are a challenge?
I would appreciate any information - thanks,
