Could it be a B28 or a B35? It comes from the same stable, namely from the Marconi Company.

This is known as a CR 150 {B28/B35 were variants of the CR 100 series} and whilst it was used in an Admiralty system for W/T Shore Station fit as the Receiving Outfit CGE, it was never used as a stand alone general communications receiver.  For that reason it did not receiver an Admiralty name.

The frequency range of the CR150 was between 2 and 60 Mc/s {yes, 60 Mc/s} and they called this a "High Frequency Band Receiver" rather than a H/F Receiver. It was a double superhet. As a system fit the diversity was achieved as shown in this diagram.
