I agree. Just the geometry of the knobs on the dash would seem to indicate a non-Packard installation. I Googled the following fromhttp://www.futurliner.com/autronic.htm

...The next clue to check the serial number printed on a paper sticker on the amplifier. If the amplifier was mounted under the hood of the car for a long time the tag maybe deteriorated and fell off. The phototube had a metal tag in the years 1952 through 59 and a paper tag between the phototube and mounting in 1960 through 66. The serial number consists of nine digits. The first digit indicated the division this unit was sent to. The second and third digits indicated what year the unit when into. The remaining 6 digits indicated the serial number starting with number one. If you run across a very high number starting with the 100,000 range, this means there may have been a minor mid year production change.
Here is a breakdown of the model and serial numbers as they apply to the various car lines;
156 000001 Chevrolet
256 000001 Pontiac
356 000001 Oldsmobile
456 000001 Buick
556 000001 Cadillac
857 000001 Lincoln. An "A" will follow the serial number 1964 and up
864 000001-B Mercury
864 000001-C Ford
756 000001 Warrant Replacement.
