Note the serial number plate on these adaptors is mounted offset.  

Early-Production 274N FT-260s also have the serial plate, but it is 

centered at the bottom.

 

My NOs-74912 ATA/ARA Manual does not define a Local Control

Adapter drawer like the CBY-23154 or FT-260 for the ARA.

If anyone knows of one marked for ARA, we'd all like to see it.

The AN/ARC-5 equivalent is the C-24, which looks a bit different:

RAT, RAT-1 and RAV radios and accessories were built in limited numbers.

50 sets of RAT, 50 sets of RAT-1 and (reportedly) 48 sets of RAV were
produced.

A "set" includes all the radios and accessories supplied for a single
installation,

i.e. an RAT set would include a 13-20 receiver, a 20-27 receiver, two
dynamotors,

two remote control adaptors, two local control adaptors, one dual RX rack,

one shock mount and one remote control box, plus minor accessories.

So there were 50  13-20 radios, 50 20-27 radios, 100 dynamotors, 100

Local control adaptors, 50 racks and shocks, etc.

 

Each one of these major components was serial-numbered individually and

independently of the  other parts.  For instance:


RAT Set #1:

13-20 RX Serial #1, Adaptor Ser.#1, Dynamotor Ser.#1 
(this was the only RAT radio with matching serial numbers).

20-27 RX Serial #1, Adaptor Ser.#2, Dynamotor Ser.#2

Dual Rack and Shock Ser.#1

Remote Control Box Ser. #1

 

RAT Set#2:
13-20 RX Serial #2, Adaptor Ser.#3, Dynamotor Ser.#3 

20-27 RX Serial #2, Adaptor Ser.#4, Dynamotor Ser.#4

Dual Rack and Shock Ser.#2

Remote Control Box Ser. #2

 

And so on.  While all of the Local Control Adaptors for these three 

radio types (RAT, RAT-1, RAV) are marked "CBY-23154,"  they are

also marked for the specific set in which they were deployed, i.e.

CBY-23154, "A Unit of RAT-1 Equipment."

Therefore, there can only be 100 CBY-23154 marked for RAT-1,

100 CBY-23154 marked for RAT and (though God knows where 

they went)  384 marked for RAV.   (100 dynamotors for RAT, 

50 racks for RAT-1, etc.).

 

Aside:  I have only touched one piece of RAV- a dynamotor,

which I gave to a dear friend who deserves to have something

RAV for his collection.  There is a rumor all the RAVs were dumped

In the Med and replaced by RAX.  I think that quit possible.
