Good sleuthing. I thought that cabinet-style looked familiar too. It's interesting how, what obviously is a prototype 7" 621, the cabinet was designed in a way that would be much more cheaply produced by RCA, and then changed to a more complicated, more expensive to produce, cabinet. I'd love to know the whole story!
