I enjoy collecting and reading House+Home magazine from the 1950's.  I recently obtained a copy of the February 1953 issue and found these two items in the "Products" column:

"COLD PANTRY.  General Electric crystallizes phantasmagoria--for showroom only

"Some builders who had the energy to brave the cavernous Merchandise Mart during the convention last month got a good look at what tomorrow's refrigerator might be like, and an inkling of the way they would have to build around it.  Accessible from front and back, GE's experimental XR-10 could serve as a useful buffer between cooking and dining areas in an open plan.  The horizontal unit has a capacity of 10 cu. ft. but takes up half the space of a conventional model because of unique "thin wall" insulation.  Finger grips are used to open its six doors; magnets hold them shut.

"Developer:  General Electric Co., Major Appliance Div., Louisville 2, Ky.

"GAS RANGE harbors dishwasher-on-wheels

"Scheduled for sale this spring is Cribben and Sexton's development of its own Wheel-about Universal gas range (see H&H, Jan. '52).  The mobile cart, designed to nest inside the range, now contains an automatic dishwasher that requires no special wiring or plumbing.  Plugged into any wall outlet, the portable dishwashing unit utilizes hosed-in tap water, regulating its temperature and pressure for efficient washing action.  Retail price for the appliance-within-an-appliance will be about $550.

"Manufacturer:  Cribben and Sexton Co., 69 W. Washington St., Chicago 2, Ill."

We know that Universal gas range & dishwasher came exact reality.  From the photo, that GE fridge looks like what eventually became the wall mount fridge, but no accessible from either front or back.
