[Alex van de Wetering]

I believe the pictures that Lynn, Jaques and Keith posted are the ones that show the original CMP mirror (screws on the rear). This is modelled after a Lucas wing mirror as used on pre-war British cars and early MV's.

The other that Svenn shows is modelled after a Lucas interior mirror (screws on the sides) as used on pre-war cars....on the dash or windscreen frame.

At least that's what I have been able to conclude by comparing pics on the web with period CMP pictures!

Both types of mirrors are available from dealers that specialize in British classics. The "interior" mirrors seem to be cheaper, so that might be the reason you often see them on restored CMP's (?)
