This post-war model, launched in 1949, was a radical new styling of the original Hawkins Tecal (pronounced tea-call). It differs from the previous model in that there is no plinth for the teapot. The clock mounting and frame are also different in shape and style. The patent, number 661601, was applied for 1949 by Lawrence George Hawkins and LG Hawkins and Co. To the best of my knowledge this model was not manufactured by Teesmade Engineering.
The 1200a appeared in 1950. I believe that this version was an upgrade to include a kettle which plugged directly into the back of the clock unit, rather than being attached by a wire.
The 1200b was launched in about 1951.
The 1200c appeared in 1952.
In the September 1950 edition of Silver Lining, there is a short article about “The Marvellous Tecal”, advertising the 1200A. The article includes this letter from Lt Cdr (L) A E Chiverton, on HMS Cleopatra, Bay of Biscay, March 29, 1950:
I was one of the fortunate individuals who heard of and purchased one of your Tecals before the war – in 1937, to be more exact. You may be pleased to learn that it has had almost continual service ever since, and is still absolutely dependable for my morning call and the added luxury of a good and really hot cup of tea.
