I have a visor that was removed from a '55 1st. I have no idea what brand. I have another '55 1st with holes in the roof that match this bracket exactly.

It also has a trim piece (SS?) around the leading edge and it appears a couple of pieces of end trim are missing.

So to answer one question- Yes, someone made a visor for '54-'55 and it doesn't attach to the center strip (which, of course is not there).
Who made this one is a mystery to me as I can find no markings or numbers. There is however what looks like a tarpaper substance gasket on the mating surface of the bracket. The ID may be under there but it is not important enough to me to ruin the gasket to find out. I'm hoping someone has one like it and can ID it.
