Identify HMV Car Radio

[Murphy Maniac]

It's unlikely that it was made for the overseas market as it is currently fitted in a 1956 Standard 10, and looks as if it has been for a very long time. The camera angle does distort the length of the knob, it has a total length from radio body to the top of 3.5cm, 2.5cm of which is the top half and 1cm for the inner collar. The two are joined together on the left hand pair to act as solely the on/off volume control whereas, I am assuming that the pair on the right will match but the 1cm deep part acts as the wavechange switch leaving the outer part for tuning.
I definitely need to sharpen my PC skills so that I can attempt a reproduction of the dial.
