Vintage Hamilton Beach slow cooker
Tim, I have that same slow cooker except that it is a Sears Countercraft in harvest gold. It was made in September 1977 by Hamilton Beach. I have never come across another manufacturer of vintage slow cookers that had the auto-shift feature. It is handy when recipes call for high heat to begin with and then lower heat after a while. Just like many vintage small kitchen appliances from that era, you should get many years of reliable service from it.
