When during WW2 the VHF AM Transmitter Type 87 was introduced it came with its own 87 receiver as an option.  It wasn't a popular receiver and unlike its brother transmitter had many problems. It was relieved by the Receiver CDU/P104.

However, not long afterwards, Their Lordships chose this Receiver, the 62H [which they called the CDV] to take the place of the CDU/P104. The choice was obviously good for it lasted out the useful life of the transmitter Type 87.

Fitted where a VHF requirement was most relevant.
