"Wonder Kitchen"
I wonder how it came to be called this, as I have not seen any GE advertising that referred to the unit as such. The official name is the "Kitchen Center" as evidenced by advertisements of the time, and the name on the item itself.
There were various configurations available, with the common parts being the dishwasher (Electric Sink), and the stainless steel top with sink and surface cooking units. Some had the washer-dryer combo, others lacked it. Some had an oven below the cooktop, others had a storage cabinet.
The one shown appears to have its original single-handle faucet, which I think is Moen. Obviously this one was at least partially Turquoise Green originally. Hard to say if all these parts were as purchased when new, or if it was later assembled from two or more units.
