It’s a half-closed horizontal Recto cab. I believe they were custom order only for a while after the main run, but since Gibson bought them, you’re able to buy them from the big chains now.Is that the older vertical 2 x 12 semi-open Mesa cab?
iirc They made a 4x12 version and a 2x12 version to play with the Road King head that changed outputs along with the channels so you could pair them up with open or closed.
