Nice grab on the RSIIIb's; well done! :thmbsp:
That paragon looks real enough, but the color is so unusual it has to drop the value. I'm betting it never left the factory that way. Years ago it was quite popular to apply paint and "antiquing glaze" to surfaces, to create that kind of "newly aged" look. Sometimes it was a good thing; my Mother did that (with the addition of some decoupaged motifs) to a bathroom in our home, as well as the kitchen cabinets, and completely transformed those rooms, for the better.
While it's possible that this color was a factory treatment, I'm betting someone took those boring old-fashioned teak veneer Paragon units and did this to them long after they left the factory clothed in the normal brown veneer. Twenty or thirty years ago, it would have seemed a reasonable way to "improve" them. No one would have foreseen back then just how much these speakers would increase in value (although they weren't cheap to begin with).
The really interesting thing is the statement that those are serial number 102, and the numbering started at 100. IF that is true, then that would probably be only the second production Paragon to be made; if not for the paint job, that fact should have made this go for more than the normal price of one, instead of a bit less.
So far I can say very smooth nice bass, better than I expected. Wasn't sure they'd compare to the watkins woofers but I'm liking them so far with my Spec-4 and Spec-1.
