Thanks Pawlus, I kind of figured the same thing (early 90's). The 7 speed threw me off.
Maybe I've been Manchurian Candidated by eBay, but Montello frames alone seem to go for 500 upwards. Though I suppose not knowing about the wheels and not fancying the group on there, I'd be kind of paying that for the frame anyway (if you get me). Anyway, it's not been snapped up so it seems you're right.
