UPDATE II: Still Available.
UPDATE: This is actually the 2nd Oneida hardtop found with a flat fender in the Spokane area (other is here). Maybe someone was converting them at the Air Force Base west of Spokane?
This top surprised me. It has a date plate! It seems to be some kind of manufactured-for-the-military hardtop. It’s made by the Oneida Products Corp. out of Oneida, New York. The manufacture date is August 1951.
