That's a huge assortment of gear, but the sale company is just shooting themselves in the foot if they aren't pricing it to move. Very few people in the vicinity are going to even know what it is, let alone pay top dollar for very old and questionable condition test gear, all of which would have to be gone through to even use.
Wait till they have to consider hauling it all out of there and then PAY someone else to have it sent to the e-waste. Doubt they would even put it up on ebay - lots of trouble to photograph, list, and then inventory and store it.
This seems to be gear from 1950-60s. Obsolete and useless today. Probably will go for a price of scrap metal. Some may actually contain sizable amount of silver and other valuable materials though.
