Historical Context:

The Whitall Tatum Company was one of the largest and most influential glass manufacturers in the U.S., operating from 1806 to 1964. Based in Millville, New Jersey, the company produced a wide range of glass containers, insulators, and pharmaceutical bottles. The “No. 5” designation suggests this insulator was likely produced in the late 19th to early 20th century, a period when Whitall Tatum dominated the insulator market for telephone and telegraph lines. The “8” beneath the number may indicate a specific batch or mold variation, adding to its collectibility.
