They have this listed as a Blitz which were budget versions available in Japan (think Greedson's Epiphone line) but it is NOT a Blitz at all. Understandable as it is Moron Go Round.
Most likely a variation on the A-1922 (see page 2 of the catalog linked below).
Still a bit pricey but in fairly good shape considering its age (approx 48 years). These don't come up too often at all any more. If you're into the early Arias this might be one to consider.
