7 series collection, USA

A picture from the early 2000s. Back row: 7 series amps, two large 7120/4120 cabs and trolley, and probably a third at right (height looks the same). Two of the amps have single central handles - probably 730s, or perhaps one 730 and an early 7120?. The 7 series amp far right is a 7120 or 760, its end handle just visible.

Middle row: four large-box AC50s, cabs and trolleys. Front row: early JMI amps (at right, two AC15s and an AC10). This is evidently only part of the collection.
