The closest I got to those was a 1977 coffee color LK washer that I bought in 2005 from a guy who was selling his fathers items in Connecticut. The washer was in good condition and worked. I had to drive about 2 hours from Mass. to Connecticut to pick it up and he had it in garage filled with stuff he was trying to sell.
About a year before that I had found the top of a harvest gold LK 1977 dryer on Ebay. It was the entire control panel, the wiring, and the actual top and lint filter. It came from Oklahoma or Texas.
I can only imagine your collection. It must be heavenly there. lol.
