This is my medium sized vintage license light clear glass lens, my mystery item.  I have no history on the part at all, merely throwing it out there for the guy who desperately needs it, AND knows what it is. The lens is has a 1 5/8" height, 3 1/16" width, and top of arch is 1 3/8" tall (above table top). I have two of these, this is the better of the two, this listing is for one (1) only.
