I apologize if this isn't the right section to post this but since this is where I found the pic:
How rare and how much would the bottom light "ROCKEY-RAY" would be worth, in decent shape with a clear dome? Was this model also available as a rotating beacon or only as a 4 way flasher, and if so, how much are these worth in either cases?
I'm asking because I might be able to pick one.
