Sargent Planes Identification and Value Guide, by David E. Heckel. 84 Pages. Softbound. In his recently published "Identification and Value Guide", Dave Heckel has provided collectors and dealers a helping hand to understanding one of the most complex, yet increasingly important areas of tool collecting. Heckel's Guide makes sense of the Sargent numbering system and the trademark type studies make the previosly challenging area of dating Sargent tools infinitely easier. Illustrated with early engravings, this book gives collectors an opportunity to see some of the rarest of Sargent tools. An excellent companion to The Sargent Catalog Collection. A major contribution to tool literature and highly recommended. $20.00 (BK-043)
