I don't have any first-hand knowledge but I believe the cabinets were made by RCA. I have seen an old RCA promotional film on Youtube that showed various steps in TV manufacturing, including cabinetmaking and finishing. I don't recall the date of the film; the cabinet styles seemed typical of the mid- to late 1950s.

Kind of a long shot, but RCA did acquired a complete cabinet division when they bought Victor. Victor made their "furniture". Perhaps at one time the Camden facilities were used to produce cabinets for many products, including TV receivers. :scratch2:
