Help with 70s Zenith Avanti

Hello, First time posting here. I recently found a Zenith Avanti at the store Waves here in New York. I was unable to get the model number from the set, because when I returned the following day I was shocked to hear that it had been purchased by MTV. It will be blown up as part of a tribute video for the Who. This seems like a shame since it's not the easiest set to find, and it has a great spage age look. Anyway, based on the pic can anyone provide a year of this set, or perhaps a lead on where I may find one? Thanks in advance for the help.
