Clyde:
I have two Ellsworth sets, a very nice tombstone, and a small chairside on short legs. For purposes of I.D., my two sets both have the drum dial and controls on each side of the set. The Ellsworth, and also the Musette radios were made by the Ottawa Furniture Co. in Holland, Michigan, with chassis suppled by the Arborphone factory in Ann Arbor. You will find schematics in Rider's vol. III, under Musette. Any questions? Good Luck!
