Query: Antique Trader Clocks Price Guide: Including All Types of Clocks - 17th through 20th Century (Antique Trade Clocks Price Guide)

A brave title with "ALL Types of Clocks" and it disappointed as it did not include many (if any) small Boudoir Clocks. Few 20th Century clocks only 1 electric clock. Few mentions of swiss clocks of note. NO INDEX - what sort of book dose not have an index.Like many American authors - if it does not happen in the USA it does not happen.I would not recommend this book to those who collect clocks from "the world" as the world is greater than the USA.
