We have a lot of documentation that the 1932 GF receiver was CBY-46006.

Before that there is the 1931 RU-1, about which nothing substantive seems to
be known.

My questions really was:  Is it likely that the CBY-46006 was also the receiver
for the RU-1 set, in addition to being the original receiver for the GF set? 
My analogy was to the CBY-46104, which was a receiver for the ARA set, in addition
to being a receiver for the RAV set.

Only some RU-1 documentation will ever answer that.

The 1930 RU is even more obscure.

The former was *both* Liaison or Command, and the latter Command only.

The RU-3 was part of some liaison sets, but it was also part of one command set.
The RU-3 CBY-46036 is associated with the GF-1 CBY-52027.

The RU-3a was part of one command set only.  The RU-3a CBY-46041 is associated 
with the GF-2 CBY-52028.

The RU-3a/GF-2 set essentially established the design used for all successor
RU/GF command sets.
