According to the McCalley book, Ford used the green shade headlight lens (6511 EX) from January of 1920 until June of the same year - when they were replaced by the fluted lens. How hard are these lenses (6511 EX) to find and what does a decent pair run for price?

Hi Ron,

I don't think that they are plentiful because, as you stated, they were in use for such a short time and after the introduction of the far superior "H" lens who would want to replace a broken green lens with another green lens? Well, perhaps a parsimonious sort, but I suspect that most folks would go for the better lenses.

That said, I don't look for them at swap meets but I have not seen any in ages. I acquired a couple or three maybe thirty years ago for a particular vehicle. They could be easily recreated with a piece of plain flat glass and green paint of the right (or close) color.

Good luck with your project and pursuit. Bill

I bought one off ebay a few years back, still in the Ford wrapper.

Actually the green lenses were used the first half of 1921, then the "H" lenses came on 1922 model year cars.

Roger - you're absolutely correct, '21 not '20.

I think I have seen a lot more of the lenses at swap meets than I ever have seen on model Ts. I haven't been watching eBad much lately because I am too broke and don't want to find something I want and should not buy. But I used to see them on there fairly often also. Price varies from extravagantly crazy to reasonable (sometimes less than $20 apiece. Most restorers don't bother with them much because they were used for such a short time. I have considered putting them on my boat-tail, but since it is called a 1919, it should have the clear lenses anyway, and that is the year I shoot for on it (although the Muncie is admittedly a bit later).
I would consider painting clear lenses myself if I had a car that really should have them. Maybe even if I had a '20 or '22.
Drive carefully, and enjoy, W2

They must all be on the West Coast because I have never seen a set at s swap meet here. Thanks for all the responses.

About twenty years ago or so, I was at an estate sale with my old buddy in south central NE. There was a five gallon bucket half full of those green visored lenses. Didn't pay any attention to what they brought or were they went. A lot of the green paint was peeling off. Dave
