F. M. Locke porcelain signals
 Fred M. Locke, the father of porcelain insulators actually had
his start in glass insulators in the 1890's. There is a great deal of
information about the man and his career covered very well by
other collectors such as
Elton Gish. I couldn't possibly do justice
to these works here.
