Just questions of curiosity OG:

Is this unit from the vintage of '78-'81?

Is it another brand re-badged?

The lettering strikes me as exceptionally plain, and i don't think i've seen it elsewhere on Altec product. For instance the 9442/9444 amplifiers and other peripheral rack gear of that era has a sort of "Altec Lansing" logo that is consistent among all of those products.

I also note that the eq in the ad seems to have "filler" plates in place of the rack ears to complete the front edge trim as if the eq came with both the fillers and rack ears when new. It seems to have been designed to compete in both consumer and professional markets at the same time, unique for an Altec product, no?
