A handbook for the recognition and identification of fake, altered and repaired insulators. Unfortunately, wherever specific items acquire a value due to their age or rarity, there are attempts to imitate and sell to the unwary.
Insulators are no exception.
This handbook outlines in detail the various ways in which this is accomplished. This booklet should be in the hands of every collector and most importantly, the inexperienced, who are contemplating a substantial investment in rare pieces.
