I think you guys nailed it. The '81 catalog shows the bike in black. Bob, can you resize that catalog page to fit on the forum here? I don't have any photo processing software at hand right now. Otherwise I will post it when I get home. Unfortunately, my image of the catalog page is a little blurry.

The Sports Tourer that I was thinking of has a large red panel on the seat tube, and a red head tube. It doesn't have the chromed stay ends, but does have the chromed fork ends.
