Mine didn't have a different label.
I have no idea where it was originally purchased, but there wasn't anything "off brand" about it.

It was a Gibson, and it was not listed in the several informational books people around me had access to at that time. If Gibson considered it a flop, it would make sense for them to edit it from some of their publications in the interest of being able to add a little extra pomp on their 'glory' models.
