02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionTC108/G chassis built ('Alvis produced only 37 chassis' in two years'): 15 bodied by Willowbrook, 22 by Graber; the archive notes a case for 39 | 371 | Factory production | Independently researched |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
In 1954 Alvis supplied the Swiss coachbuilder Hermann Graber with a TC21/100 chassis and asked for a closed body that could be put into production in Britain. The result was a graceful two-door coupe with four seats, also made as a drophead, and the engine was tuned to 119 bhp. Only a few were built by Graber and production was then switched to the UK, though some enthusiasts prefer the lines and detail of the Swiss-built cars.
