Sort of looks like the fairing a French company made for endurance racing cb's.
Someone posted a link to a european site with a bunch of different style racing bikes that included rickmans, seeleys, dunstall and dresda CB's, these french bikes were among them and they were without a dout Fugly! but for some reason I was drawn to them, like a moth to a flame.

I was just about to ask what kind of bike the bat bike was!
