      Hello,
      Check the Links section of the group for the Sunbeam Service Bulletins -- C20 thru C30 models. The Bulletin for the C50 is in the Files section. The C30AB is the same as the C30A except for the "Beehive" glass upper. The nameplate on the bottom has a letter "B" stamped after Model C30A. It is Korean War vintage -- 1950-53 copper restrictions time frame and came with a certificate for a replacement metal top which could be obtained from Sunbeam when its production resumed. There is misinformation on some sites about it being WWII vintage, but Sunbeam did not make appliances during the war, and the C30 models did not start until 1948. The other Sunbeam pots you mention predate the automatic Coffeemaster and I believe they were produced in the early to mid-1930's.
      Regards,
      John A.

      > > The patent dates listed on the Coffeemaster nameplates are often confused with dates of manufacture, and this has led to some mistaken assumptions about the age of the different Coffeemaster models. For instance, there were no Coffeemasters manufactured during World War II. Sunbeam stopped production for the duration and did not offer the Coffeemaster again until late 1945, and when they did, it was the C20B until 1948. The Model C30AB with the glass "beehive" upper bowl, which many assume is World War II vintage, was actually offered in the early 1950's. A world shortage of copper and fears about the Korean conflict led the National Production Authority, operating under the Defense Production Act of 1950, to set limits on the civilian use of copper that lasted from early 1951 until 1953. Thus, Sunbeam manufactured the glass bowl for the C30A in order to continue Coffeemaster production and comply with NPA orders at the same time. By early 1953
      copper restrictions were lifted, and at Sunbeam, the C30B was born. The C30C came along one year later. Less clear are details about Model C40. Advertising indicates it was available in 1956, and it seems to be a contemporary of the C30C, only with an aluminum upper bowl. There were other, sporadic shortages of copper between 1954 and 1956, and Sunbeam may have manufactured the C40 aluminum bowl as a way to keep up production and maintain a steady price for the Coffeemaster.
