AH! I hate it when that happens, which is quite often. That cabinet is called the "Flourentine" and was first introduced only as a rectangular CRT using the 25MC36 chassis in 1965. The cabinet was last offered as a '67 model like yours. It was one of Zeniths highest end cabinets too, which unforutnatly the higher end the cabinet, the greater the probability its been gutted when spotted at an estate sale.

Heres some pics of what the TV looks like, this one has the large 25MC46 chassis though.
