Mold Variation

Locke Hi-Top Style

At left is the "Locke Hi-Top style" mold variation, which only appears on some earlier experimental number 68 styles. This mold variation is named after the Locke Hi-Top porcelain insulator with the same features.

There are two distinguishing features of the Locke Hi-Top style: the top wire ridge has an extra "step" and the ears are flatter.
