Antique expulsion type glass arrester

By Jbaker, 14 January, 2015
Description

Lightning Arrester found on very old transformer. Expulsion type with glass housing. Has LM etched on glass. Also has name plate on the copper base. The Line Material Company. Milwaukee Wisconsin. Type PF. Expulsion type. It's my understanding that The Line Material Company merged with McGraw Edison in the 40s and ceased using the LMC name.
