The TC21 was not marketed as such – it was the Alvis Three Litre, as was the TA21 which preceded it. It was only the marketing department that came up with TC21/100, the emphasis on the 100 being for both bhp and mph.
Total production over the short period 1953-1955 was 726, mostly Mulliners saloons, but including 100 Tickford dropheads and 26 Grabers.
The Tickfords have survived remarkably well with about one half known to exist.
If you own, or did own, a TC do please make a comment below to record its current state so we can update the records.
The last published AOC register of the TC21 and TC21/100 models was in May 2003 (Number 32) when Colin Newby was Model Secretary. A small number of printed copies are still available in the archives.
