Kenneth L. Cope

In response
to popular demand, Ken Cope has fully and completely revised his
original groundbreaking book on the wrench, one of the most mechanically
intriguing of all tools. In this revision, the author covers an
additional 20 years of wrench-making and adds almost 200 new entries
to his identification and description of wrench makers. In addition,
he has made additions to 60 of his existing entries. As before,
each listing shows the maker's location, history, period of operation
and known products, with profuse illustrations taken primarily from
catalogs of the period.
