what's the BB threading? I'm just fixating on a few features that make me think "Italian": the brake arch, the forkcrown...I know it's much more likely to be something from Taiwan, but Performance WAS bringing in framesets from Italy, at least I saw a few in the stores (maybe not in catalogs) in the '80s. Did you see any markings on the fork steerer?
Nah, on second look they could be Long-Shen frame bits so it's looking less "italian" to me now.
