Either Philco did sell chassis to custom cabinet builders, or else people had their chassis pulled from original cabinets and installed into custom aftermarket cabinets...or both. Probably both. Philco obviously sold chassis to the Radiobar Corporation and Columbia Mantel Company ("Singing Fireside" fake fireplaces with a Philco radio built-in), so I would not be surprised if they sold their chassis to a few other companies as well.

The problem is, unlike Zenith, there doesn't seem to be any records of Philco's activities prior to the Ford takeover. I had heard they were in the Ford archives, but the Ford archives are now part of the Benson Ford Collection at Dearborn...and looking through their online catalog...their Philco holdings seem to be limited to Philco annual reports from the 1940s and some advertising material. I hope this doesn't mean the original archives have been lost or destroyed.
