There is an interesting Decca "trench" portable in the collection of the Science Museum (Exhibition Road, South Kensigton, London).
I stumbled on it in this web page yesterday while looking for something entirely different.

When they say the reflector is 'unusually made of copper rather than the more common aluminium' though ................ I thought the copper reflectors just had a copper type coating on top of aluminium ? Were they actually solid copper then ?

You're right, the copper finish is a plating, not solid copper. You can see the base metal in the edges of the bullet hole.

Re: Interesting Decca Trench Portable
Thank you so VERY much Oedipus !
I was worried for a moment as the two I have with copper reflectors clearly show they are not solid copper.
Phew !
