Just got the three volume set of aucton catalogs for October 13/15 inb New York at Sotheby's. I predict that this box set will become an collectors item in its own right. There are over 1000 lots, about 1300 timepieces. Many described in detail, a total of over 700 pages. Catalogs available at www.sothebys.com Not cheap but well worth having in ones reference library. The top piece is Mudge's green chronometer for 1.5 to $2.5million estimate. Also Harrisons wooden movement tallcase for $500'000 to 1 Million, and many more.
