Same "arm" as in previous and following photos except with insulators upon their pins. Note how the insulators sit upon their pins and that some seat above the wood arm and others close to (and some actually sat on) the wood. The latter sometimes created "fossiled" wood grain imprints upon their insulators' base rims. In other instances, the glass cracked or fractured because of physical stresses from the heavy cable squeezing the insulator down into the wood.

Note: All of the insulators photographed were uniformly tightened onto their pins; illustrating an example of their mounting and base rim-contact irregularities.
