Brush Problems Don't Stay Answered

... because Stackpole Engineering Progress makes yesterday's developments out-of-date today.

It pays to check brush requirements for all types of rotating electrical equipment at frequent intervals against the latest that Stackpole engineering may have to offer. Brush engineering is a fast-moving business, and Stackpole engineering is the fastest-moving of all. 

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.
