Can you supply us with more details? Things that would be helpful: what brand (appears to be a Vetter knock-off); will it take a Vetter/Windjammer replacement windshield; what (if any) mounting brackets do you have for it; will it work with a Vetter mounting bracket; can you take photo's of the other side to show what pockets it has, if any; is the wiring complete; what is your asking price; will you ship it, and from where, and how much?
I am not in the market, but these are questions I would have if I were interested in it. The more information you provide, the easier it is for potential buyers to know if it is what they are looking for. Cheers!
