Got a reply from Parabellum, they're interested in making windscreens for Zero's but they need a loaner to design it. Too bad that I live a continent away from them.
Anyway, did some more digging for a nice fairing and suddenly remembered on of Vetters unfinished projects, the Alcan:
More or less the future generation of the Windjammer. Too bad it never went past the prototype stage because I frigging love the thing.
