Only one with this color I've seen right now was an 83 model provided by rekmeyata on the "saved from the dump" thread, There's also one with the same color on feebay right now.

Here's a brief catalog info on it: http://bikecatalogs.org/SCHWINN/1983...per_Sport.html

Something different on the catalog besides the color and most of the components is that it mentions Reynolds "531c" tubing and nuovo record derailleurs.
