I've seen a few Rosses, Curt--mostly in the early '80s when I lived in Winston-Salem, NC. So my guess they're time-frame okay.
Some of them were pretty nice, but I remember some dogs, too.
I friend of mine had a Ross, though I don't know if it was a Signature or not. It was fitted with Shimano 600 abaresque components, if I recall right. But I don't know much more than that.
I don't think they had fluted stays, though. . . . <g>
