The D21 was manufactured from 1949 or before, to about 1954. There were several different versions of this model.
This D21 owned by Doug has a confirmed date of 1949, when it was given as a wedding present. The construction is almost identical to the D20, with its cream coloured textured paint, wooden tray and teasmade unit and cube shaped teapot. The square clock is fashionably trimmed with chrome.
I am most grateful to Alex for these pictures of his early D21. Alex’s D21 is serial number 29104. Bizarrely the switch stalk on the left is longer than that on the right, which is consistent with John’s model below.
The teasmade instructions are helpfully printed on its body. The standard alarm clock triggers an electric element in a kettle. As the water in the kettle reaches boiling point the pressure forces the water through a tube in the kettle lid into the teapot. The teapot fills and the empty kettle unit rises, simultaneously switching on a light and an alarm.
Edi, who lives in Switzerland, collects teasmades on his visits to England. His boxed D21, serial number 33944, is pictured here with its outer label and instruction leaflet.
Here is John’s D21, bearing the later serial number 48817. The teapot is similar to the D25, (except that the corners of the polygon lid are not as pronounced). Whilst the clock surround is square with a chrome surround, the face itself is circular. The kettle has the standard dimpled metal finish, spout and handle of a Goblin kettle but no maker’s name. The lid is shallower than the subsequent D25 lid, and the handle is secured to the kettle by rivets top and bottom, unlike the D25 handle, which is riveted to a strip which is then brazed to the kettle corner. The most significant difference is that the kettle is made in two halves, top and bottom, and has a central seam.
Mike’s even later D21, serial no is 54643, is pictured here. The clock face once again has a square design.
This 1949/1950 example of the D21 is in Doug’s collection. The round clock face is the same as that fitted to the Timespot radio. Doug feels sure that surplus stock was used up on Teasmades as he has a later one which reverted to the square face. This example was sold to Doug not working but he soon fixed it and it is excellent condition. It had one owner who died in 1982 and it had been stored since then.
This advert from 1949 illustrates what appears to be a D21, still in production with the square teapot design. The price is itemised both with and without a tray, crockery not supplied. With tray – £15.9.0, without tray – £14.7.11. I have an even later advert in an electrical catalogue dated 1954 which lists the Goblin D21X at £12-16-6 (wholesale). The casing is identified as being made of plywood.
