These are pages taken from the book: The Telegraph Manual by Taliaferro P. Shaffner 1858. They describe an insulator which recently sold on e-Bay which as of date, there are only 2 specimens known to exist. The insulator is referred to by collectors as the Reid's insulator. Hopefully there is enough resolution in the picture to be able to view it!
