William B. Fenn (1813-1890) had a sizable business producing and supplying decorative stenciled clock case components and reverse decorated glass tablets for clocks between 1840 and 1863. He was a major supplier of ornamental clock glasses to many manufacturing firms in Plymouth, Bristol, and the surrounding towns. Among his customers were the firms of Seth Thomas, Silas Hoadley, H. Welton & Co., Terry & Andrews, J.C. Brown, Brewster and Ingrahams, and many more. This book is a replication of his more important stencils from the collection of the American Clock and Watch Museum in Bristol.
