Buick-Powered Sawmills

[Al_Smith]

This one was a odd ball .Two 12v71's with a large generator  between them,back up for a local telephone company .They were tuned by using an exhaust pyrometer .The danged thing was 208 volt  which was really odd .That and several large Cummins engined back up's supplied that 3000 amp 208 volt service .I've never before or since seen anything like it .
