About These Maps
In 2014, anonymous donor provided us with a wonderful set of fragile insurance maps describing the Wiley & Russell Tap & Die Company of Deerfield and Greenfield, Massachusetts (1872-1912). Along with the Well Bros. & Co., these two operations became the birthplace of the global machine thread cutting tool industry. This page provides you with access to these maps. They are the basis of our virtual reality model, which you may visit HERE.
