Not sure if it matters but the manufacturing company is only about 20 miles from the Marceau/Ford home in Beaverton/Aloha.
freefallzzzz--What do you make of the David Feathers I found listed as MIS at Kach Machine Works on N. Ballast in Portland. Different guy?
I saw the connection with the battery company and Deka batteries. Here's the address for the company headquarters:
East Penn Manufacturing Company, Inc.
Deka Road
Lyon Station, PA 19536 USA
I wonder if Feathers drove cross-country--back and forth to Pennsylvania?
