I don't like the dog pee or whatever it is that was sprayed on the lower grille, but other than that they look nice and complete. Oak and walnut were both offered, this is of course oak, which had brown grilles but the grille cloth is not original. They do appear to be original grille frames (from what I can see) which is good. They are also on what appear to be the original risers, most are not so that too is good.
I've been watching three pair on eBay for the last month or so. They're hard to sell on-line because you really need to be able to pick them up to make it worthwhile, they seem to languish for sale for a long time between $2,500 and $3,500. I feel that they're well worth the $3,500 considering their SQ and overall quality if all of the original pieces are there and working properly, but getting that price is not easy. More likely they will sell for $3,000 or less. Two local buyers and that number climbs, only one local buyer and not so much.
They are hard to find near you when you're looking, but so are buyers so prices just don't go that high. Such is the nature of large speakers.
Expect to service the crossovers, original PIO caps are usually degrading by now.
