1st and best edition of one of the key books on pocket watches.
Red cloth boards, frontis portrait, 490 pages, numerous excellent line drawings of escapements (mostly by Henry Wing) and important biographies of many makers with portraits. Large format, published after the author's death by his widow, New York, 1st edition, 1941.
Wonderful information, a terrific read, and a much better size than the smaller and inferior reprint.
Contents in good clean condition, but no dust jacket (as usual), and the covers stained from what looks to be a workshop environment, and hands - priced accordingly.
