I have just fitted the mirrors as suggested by Planenut. They look very neat and work well on the nearside, but do not have so wide a field of view on the offside. Probably get used to that and at least they don't vibrate. So I fitted a rear view mirror on the Faibourne central pillar. Melvyn Rutter can supply this as a bolt on accessory, but didn't currently have any in stock, so they just sent me the mirror alone.

Agree with your findings Tim both good and bad, regarding the Lucas style mirrors, so will also be fitting the central rear view mirror you have sourced to my Fairbourne screen pillar.
Spoke to Melvyn Rutter yesterday, they expect to have the mount spindles available to complete the kit in about 10 days.
