I am looking for headlight lenses for a Model T Ford that have turned purple. These are easily identified by the unique shape (see first photo) [id=403233634] and "Ford" script lettering with the letter "H" immediately below.
Insulator people tend to be glass people, and glass people tend to notice purple. Seems like a good way to put a few more "eyes" out there on the search. Maybe you'll see one in an antique store or flea market ? Any productive leads rewarded.
