That Portaflex is a modern non-flip-top cab (either the 1x15 LF or the 4x10), and what looks like a repro amp on top (because of its extreme cleanliness).
That guitar amp is a recent one from the failed GVT line, perhaps 5 or 6 years old. While technically true in that it is discontinued, I would not call it an "old" model. I liked them a lot, but they didn't do anything that my four other Ampeg guitar amps didn't, so I didn't jump on them. I regret that sometimes.
These are examples of the old Portaflexes I was talking about:
B12-XT guitar amp (there was a 4x12 version of this as well; they are like hen's teeth).
B15 bass amps, earlier blue and later black
The B15 bass amps are the ones most people know, but there were all kinds for guitar and bass, with speakers from 12" to 18", and even some as large as this.
P.S. I assume you already know that on a Portaflex, the head is mounted to the top panel of the cabinet, and the entire panel is unlatched and flipped for storage, placing the amp hanging upside down inside the cab.
