I have some 4" diameter Rosen accessory mirrors that need new glass and metal repair. The mirror glass appears to be secured by rolling of the metal backing edge to the glass. Convex glass would be preferred. Does anyone know who has replacement glass or the capability of restoring these?
you supply the mirror, and any speedometer shop has the tool to roll the edge open, and crimp back
Marc, there is an even easier way to do the job, and possibly cheaper too, than the helpful suggestion Clayton made. I have fixed three pairs by first breaking out the old glass. This way there is no need to risk damaging the metal prising up the rolled in lip. Then you have access to the mirror head to do any repair work/dent knocking.
I have my ordinary household type glass replacement shop cut new mirror glasses to suit the heads. They can match the diameter exactly, just enough to drop the glass into the head. It is a simple job to fix the glass in place with an all round bead of black silicone. An added benefit is the easy fix again if you happen to break one of your new glasses.
Hope this helps.

If you're having the glass replaced, you could even have slightly convex mirrors installed, not stock, but would give a wider field of view.
I have repaired one with a O ring to hold the glass in. They are available in various diameters and thickness. Any good Hyd.shop will have a good selection.
There was such a period mirror with convex glass called the "Mirrorscope" by the "Alexander Mirrorscope Co." It's a 1920's era item, so it slightly predates Marc's, but the idea was there.
I appreciate these good suggestions. All the Rosen mirrors I have seen for automotive use have flat glass, but some for aircraft had convex glass. These were used in biplanes to allow eye contact between the occupants the front and rear cockpits. That is what I want to use them for.
