There are two types Alan. Are they Rubbolite or Hella?
The rubber that holds the lens in rots.
I have new rubbolite lens.

Mine are Rubbolite, Brian. Are the rubber mouldings also available? As worth replacing those at the same time, otherwise would have to resort to a strip of insulation tape to help prevent lens from coming loose.

The base plates are not availablle, the lenses themselves are very rare indeed so you should expect to pay very handsomely for one. A few blobs of silicone inside the rubber will keep the lens in place.
