Wow, what a beautifully preserved and beautiful kitchen! Too bad the cabinets are likely already gone! But those appliances look lightly used and well cared for!
I'm surprised that since they outfitted the kitchen with what appear to be TOL built-ins and paid a premium for a coordinating stainless refrigerator, they didn't go with a fuller featured two-door model. I think Hotpoint probably offered one at the time.
