Congrats with your deal, Jason. Both the 85-210/3.5 and KT6-2x are quite hard to find! The 85-210/3.5 is an exceptionally sharp zoom! I own one myself, and I'll probably never get rid of it.

AFAIK not very many of these were made, as zooms in those days weren't as popular as they are today.
The weren't as 'popular' because the were expensive, very expensive!
Fast zooms were quite difficult to produce (still are), so they ware pricey!

If I were buying this lens out of LBA, I'd price it slightly above the A 70-210mm F4.
IMHO, that's waaaay to low.
I would pay that for the close focus attachment lens alone! It also fits 4 of my FA*'s and results are stunning!!!
Of course it is very difficult to value this lens without some kind of reference price, but (now knowing the lens, its optical qualities and the high 'lovability'-factor) I would be happy to buy it for lets say € 200-300 (so $ 250-375). The K T6-2x mostly scores between €20 and €40 (or $ 25 to $ 45) sometimes higher (incl lens case, paperwork...).
But if I were in your shoes... would I sell a 'once in a lifetime buy'? No. Would I sell it for a Bigma...? No, no, no, nooohooo way! ;-) Am I an LBA-victim? Hell yes!!!
