There are some good bits in there. I see what is most likely a pair, one for sure of 1505B horns, at least one 1005B, some 203's i think, some other long throw, possibly mantaray horns. It appears that the 612/614 cabinets may all be loaded with 515B, they only show one. There's a lot of stuff that's just hard to be sure what it is thanks to the comprehensive photography. The multicells need proper handling, they're a bit delicate just under their own weight. Those are not being handled well currently and will reflect on what an informed buyer will pay.
IMO, that lot should bring somewhere in the 3000-6000 range, If an informed bidder takes the time and investment to inspect it before bidding, there may be much more value there than can be seen in the pics.
