The Seller Is Mistaken:
The showpiece of the collection is not that range - it is the Lady Kenmore dishwasher, the same TOL DW I bought my mom in '73. For all the bad rap D & M DWs get, it worked very well for a lot of years, and had more features and cycles than anything else I ever saw.
The range is remarkable as a survival - Sears ranges didn't usually hold up for this many years.
The color is Harvest, of course, not Yellow. The seller seems not to realize that colors varied slightly from manufacturer to manufacturer.
