I'm mildly offended: Vintage Altec Speakers 2 Full 2 Mid High 12" and 4 5 Tube Efficient 1964 | eBay

EIA code and general appearance including the basket shape indicates Oxford as the manufacturer.

In fairness, a speaker company by the name of "AZTEC" sourced many OEM driver from Oxford. Seller may have mixed up the names Altec and Aztec, wouldn't be the first time i've seen that.
