It's well known that the

I would say that Schwinn used left over Paramount badges for their MTB's (maybe others) after Paramount switched to the decal head badge instead of metal.
These bikes came standard with "High Sierra" headbadges. So far we have only 2 documented examples having Paramount badges, and both were built on the same day. I'd say this sounds more like they ran out of the proper badges that day, and rather than hold up production they grabbed some Paramount ones.
