Your quite correct, there are some very silly prices paid for NOS Lucas D lamp lenses on eBay.  Have seen in the $50 to $60 dollar mark.
Interestingly the Vintage Car Parts site in the UK advertises replacements for £8.50 plus shipping 
D amp replacement red lens :: Vintage Car Parts  they are specified as "glass" not just "lens" so I am assuming they are not plastic.  Don't have a need for one just yet (have some spares) so have never ordered from them.  And I do prefer to but from Anthony Pearson of Classic and Vintage Bulbs in Adelaide 
Page Title if only to support Aussie businesses and to keep the dollars in country.
The other spares that I am interested from the UK are the springs etc which are frequently rusted or missing.
