10 3/4" high by 3" diameter
This early iron shelled insulator is generally attributed in early literature to a Professor G. W. Benedict and dates to approximately 1848.
It bears resemblance to Batchelder insulators insofar as the wire attachment scheme at the top of the insulator is concerned. The mounting shaft was set in the outside iron shell with solid moulded glass. All of the solid pour styles were prone to cracking and were, therefore, unsatisfactory. This piece was found in upstate New York and was apparently used on the Vermont & Boston Line. There are less than 20 known specimens which were found in a basement in 1994.
