Just found this old chap feeling sorry for himself in Halifax. Cash was exchanged and I've brought him back home to chill out with his Orange chums.
On first inspection he seems to be a tired 89/90 with a mix and match of mince parts. Looking a little closer though and there's a few stickers that prick my interest a little more.
As you can see below it has a 'Prototype' decal on the top tube in the correct font. This is followed by a 'Hand Built' on the seat tube, a 'Prestige' on the seat stay, some thing I can't read on the chain stay that is the same style as those on the Formula and to finish off the forks have 'Prestige' decals on them. It also does not have a serial number
Chap I got it from said he's already asked Orange and they had said it was a hand built prototype but I think I'll contact them directly to find out exactly what's going on here. Maybe they were trying a Prestige rear on a Clockwork front? Maybe they were trying a new geometry (it seems more upright then others from the period)? Maybe it's just a load of old pants and nothing special?
I'll investigate and report back
