I am looking for someone who can replace the mirror glass in a round side mirror made in the 1930s. The mirror was made by the Rosen company and was probably sold aftermarket for use on cars, though the one I want to repair was original equipment on a biplane. The mirror shell is chrome plated brass, about 3-4" in diameter, and the metal edge was rolled to hold the glass in place. A slightly convex mirror glass was used originally. Any ideas?
Any good glass company should be able to cut you a piece and mount it.
A quick unorthodox fix is to stick on a blind spot mirror over the broken one. Have done it, and works well as the older mirror had lost its effectiveness.
Mark, I have an amusing story about such a repair, as story which may be of help to you. An acquaintance was fritzing about how to get a mirror lens with badly damaged silvering out of a mirror such as yours without damaging the crimped over edge of the mirror back, and asked me for help. One sharp rap with a hammer had the pieces falling on the floor and nil damage to the mirror back. The look on his face was priceless!
I have the new glasses cut to a neat fit in the mirror back and simply use a bead of black silicone RTV to hold the glass in place and seal the back against moisture intrusion. Good luck finding a convex glass just the right size for your mirror head.
Hope this helps.

I think your solution is the best, if I can find the right convex mirror. I have a wet grinding wheel that was used for stained glass work. I will try to grind the edges to make a glass that will almost snap in place. Hopefully the silver will stay nice at the edge through the process.
