but the M3W version has a custom straight mount to the Fairbourne (maybe MMC) windscreen so price higher. You would need to contact them for price/availability.
Interesting. I made up a Spitfire-style circular rear view mirror, with a shower hinge exactly matching the Fairbourne screen's central column, with the hinge glued to the correct position. The circular mirror was a convex mirror for truckers so didn't super accuracy for angle... prototype failed when an emergency stop (initiated by a pheasant impatient to cross the road / lose a few feathers) caused it to flip off... back to the drawing board!
