Hello. I confess I don't have the gas globe flash drive/book because a) I never find them and b) can't afford them. Having said that I've found two of the pictured lenses. Would someone in the know please providecme with their value. These are 15". Thanks in advance for your assistance.

IMO $700-900 for the set

The 2016 'book' has these listed at a value of $850.00 to $1,250.00.

Remember, that's a price range from 2016.

Later . . .

Jim

Thank you Coltex and Jim for the information.
