To repeat and expand a comment I have made in explaining the Navy's 
electronic equipment nomenclature system in the past, the Radio Set nomenclature's 
suffix number was usually incremented with every new contract.  If there 
were no changes to any of the components, then they carried the same Navy Type 
Number as in the previous contract.  If the changes were relatively minor, 
then the Type Number remained the same but the suffix letter was incremented. 
 If the changes were more significant (as in the split between Liaison and 
Command versions of the RU receivers) then a new Type Number was assigned.  
The Contractor Code preceding the Type Number varied as the Contractors 
changed.  But if two or more contractors made the same component, the Type 
Number did not change.

Thus CBY-46048D and CW-46048D are the same, and if the nameplate is 
missing, not specifically identifiable.

If the same component was used in multiple sets, the Type Number did not 
change, regardless of whether the Set Nomenclature changed (as in RAV and ARA) 
or the suffix number was incremented (as in late RU-11 and 12, and all 
RU-18 and 19).

According to a footnote in the RU-5 manual commenting on component 
interchangability between various number suffix RU sets, there was an RU-3 and an 
RU-3a or RU-3A.  Presumably the former was Liaison and the latter Command.
