My thanks to "Scott Morgan" for the details of these rear view mirrors, I saw them on his car and thought they looked good. Listed on Ebay as Lucas style chrome round exterior wing /door classic car mirror. Item 321698142306 and are £25 for a pair. They are slightly convex and give a wide view, best of all you can see what is behind you as they are not a blur on the move, like the originals were.
