I don't know how to get in touch with the guy who owns the '41. The truck is in a fenced in area with no contact info around. When I went to see the truck last year, I called him at the number on his classified ad and he met me there. I haven't seen it advertised in awhile and I don't have his number anymore. I'll see what I can dig up.
As for the color difference in the lenses, is it possible that the sun faded the original colors?
