Jeffrey R. Wood, creator of the Standard Electric Time Co. (SETCO) pages of clockhistory.com, passed away in August of 2018. I will maintain the SETCO web pages in honor of Jeff, but will not be making any additions or changes, or answering any questions. It is hard to express how much I miss Jeff, his friendship, and his wonderful contributions to Standard Electric and Westclox research.
