Here is a nice lot of earlier reference books. Gerald Brown: Collectible Porcelain Insulators, 2nd ed. with supplement. Tibbitts' A Guide for Insulator Collectors. Vols. 1-3 Frances M. Terrill: Rare Insulators with Prices, and Hemingray Insulators Priced. Most show very little wear. I am asking $30 plus media mail shipping for this group. |
