One more odd question why are so lens amber is it a result of the gas lights or an option. Our 12 T had plain glass amber lens when the car was bought in 1960 and clear was installed by my father. And again Thanking you in advance Colin
Amber glass is the result of some type of impurity in the glass of those days in combination with being exposed for sunlight for decades in sunrich states. We don't have any amber lenses here in Sweden..
They're collectible and sought after by some. Should rob some light, though
A few years ago, the amber lenses became popular with stain glass artists. Some of the designs were very unique.
