CMP mirror replacement

[Jacques Reed]

Thanks Keith and Lynn for your info.

Looks like CO1Q 17702-C confirms it all.

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 (?)

If your mirror frames and the glass are in good shape, but the 'silvering' on the back of the glass is starting to deteriorate, check to see if there are any shops in your area that deal in mirrors.

Sadly, this seems to be more of a "Disposable Age" we live in today, but 30 or 40 years ago around here, it was possible to have mirrors resilvered for a fraction of the cost of buying new. If you are dealing with a smoked glass, curved mirror, and the glass is solid, that alone is irreplaceable today and worth getting redone if you can.

Cheers,

Locally one of our guys went to a glass shop and had a matching round convex mirror cut to size and it matches the originals perfectly.
he had to pay for several as it is very hard to cut the curved mirror and a few were sacrificed in the process. but still came out at about $20.00 a piece.

That is good to know.

While savouring a large beer mug full of tea a short while ago, something jogged in my mind that the silvering process for mirrors at one time involved use of a mercury based compound applied to the glass. Unless that process has changed recently, it might be hard to find a place willing to redo an older mirror of any kind. The very thought would likely send the nearest environmentalist running and screaming into the woods!

The part number : CO1Q 17702-C
In that part number, the "C" indicates a revision of some kind to the drawings. It could be as simple as a change to the mounting bracket, or as major as the curved glass. Without seeing an "A" or "B" type we will likely never know.

That said, every mirror I ever came across for the CMPs was curved. I also had success cutting other similarly curved mirrors to replace the glass. I believe the original AVGP mirror glass worked out OK.
