Check this one out. Seller is offering 17 hones in one sale, including what looks like two really nice sized Eschers! Most of the others look like relatively low-priced barber hones, but I don't know for sure because I don't really collect them. Anyway, the guy has a reserve price set, so who knows if there will be any bidding on this to make it worth watching. Here's the photo and link:
