Look closely at the Fluid-Drive assembly Peter, its the Hotpoint version of the Fluid-Drive. Its a Hotpoint designed Beam machine. I suspect that this drawing came from a earlier Hotpoint patent and since GE by then owned Hotpoint it makes sense that they can use it. All the Hotpoint patents have GE in the name.
It does resemble a Hotpoint/GE. At first I was thinking Westinghouse, due to the funky fabric softener dispenser, but when I saw Mini-Basket, I knew it had to be some sort of special design Hotpoint/GE model.
