They're on ebay now.
That's an interesting visor on the 26 touring. I wonder how they attached it.

Dave I agree very interesting observation
Richard do you know when this came, the year around?
I don't know what year they were sold but have seen 4 or 5 pictures of them on 20's cars. Mine has small remains of a blue-green plastic-like sheet in the grooves. It may have been tinted Isinglass.
