This is a vintage Whitall Tatum insulator # 1, CD 154, embossed "made in the USA" along with the number "37" beneath the company name. The aqua blue glass insulator is marked with a W over a T inside an inverted Triangle. The #1 insulator was produced between 1922 and 1938 and was intended as an insulator for telegraph or "personal communications" lines. Whitall Tatum of Millville, NJ, mass produced insulators in the 1920s and 1930s until the company was purchased by Armstrong, and later Kerr. My father found this antique insulator on an old telegraph line running along an abandoned railroad track more than 40 years ago. The vintage insulator is in nice condition, free from breaks or cracks. Embossing is still sharp. Clarity is good but effected by a line of rusty discoloration running from the neck to the bottom on one side. (See Photos) The old telegraph insulator measures about 4" tall and 3.5" wide.
