Original 1943 electrical trade vintage ad for SPRAGUE SPECIALTIES COMPANY.  Main office and plant was located in North Adams, MA.

Manufacturers of Koolohm Wire-wound Resistors.

More Watt-Ohms per Cubic Inch... greater dependability, easier mounting, less weight.

Koolohms provide the highest wattage ratings and resistance values in a given volume, with safe resistance wire sizes.  Deliver their full wattage ratings regardless of resistance values. Can be mounted easier and quicker and less space, directly to the chassis or grounded parts.

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.
