Ebay Item number: 7542264595
Looks like a newbie (only 5 feedbacks) and another Ebayer got into a bidding war, ended up over $22 when you include the shipping. I bid on and bought the same manual a year ago to replace the tattered one I already had, and I think I paid less than half that, postage included.
I bought a few unusual and unique old germanium transistors on Ebay and figured they were worth a couple bucks apiece max, so I bid a bit high, because at the time I didn't know if there would be another opportunity to get them (later it turned out that the seller did have several more auctions of the same). Some idiot luser with zero feedbacks bid up the price almost to my max, so I ended up paying a lot more than the later auctions. This luser later had a negative 3 feedbacks, the SOB won a few bids, then NPB'd the sellers. I'm beginning to think that he might have been a shill for some seller.
Yeah, yeah, I know. Like Jimmy Buffet said, "..but I know, it's my own damn fault." Parrot head!
