Variously these units were termed Pilot’s Selector, Control Unit, Flight Control Panel, Switch Unit and perhaps other names. They just had different arrangements of controls and shape. Your prototype would seem to be closest to Ref No 6T/207 Control Unit Type A, Smiths “Code” (ie: part No) 118 EAP. Similar to those fitted to the Beverley, Valiant and Victor Mk1 I think, but not Vulcan. The later Victor Mk2 had some different knobs and the Vulcan Mk2 version was a smaller size without the turn control or pitch switch.
Perhaps part of a Bearing plate (similar to that used by the Observer Corps, see below) evidently incorporating part of a sextant.
This is not what you requested and probably you have this anyway but just in case you haven’t here is an extract from AP4515C Part 1 Section 2 Chapter 5.
Drywick,
The Rotary Transformer Type 31 was used in the Power Unit Type 35 and 35A part of the Wireless Receiver Type 1155 and Transmitter T1154. See also AP 2548A for details of the receiver R1155.
