Interesting lenses on this T for sale
Those lenses look like glass bunt cake pans or pie pans. Very neat.
So what is the purpose of the thick lenses??????
I believe those are the Dillon lenses.

To add to Ken Parker and Ed in California -
On a high resolution PC screen, I can see "Dillon" on the headlight lens in the third photo. Hover the cursor over the photo to magnify or double click on the photo to see a larger version.
