<p>Original 1943 electrical trade vintage ad for<b><span style="font-size: 14px;"> OHIO BRASS COMPANY. </span></b>Main office and plant was located in Mansfield, OH</p><p> Manufacturers of Power Line Insulators. </p><p>It's No Trick To Make A Strong Insulator.</p><p>Let's not over-emphasize the matter of brute strength in suspension insulators. It's no great accomplishment to build a strong insulator, or everybody wouldn't be doing it. The really important side of the strength story is the ability to build insulators to a definite strength standard, and then not miss that standard in any number of times. In 1978, Hubbell, Inc purchased the Ohio Brass Company.</p><p>Unbound from a 1943 electrical engineering magazine, this unique old one-page advertisement would display beautifully matted and framed. Nice graphics. World War 2 propaganda. A fabulous addition to your retro electrical library.<br></p>
