Rollei TLR Prism Eyecup

Can anyone shed any light on a replacement souce for the above item. Over time these can become hard and distorted. Any ideas?

They are available new. they have changed in that the rubber is thiner and softer and shallower. The new screw size is the same as the old as well as the new diopters.

I just looked here at Robet White for it and they don't list it but you might email them and ask. Also you could write Harry Fleenor and ask him where to get one.

Many thanks for both of the leads. I shall try them tomorrow
