Four EX182 cars were built in 1955, three (in Racing Green) were registered for Le Mans, two to run, one in reserve which probably would (and finally did) race, and the fourth (oddly enough in Red paint) for testing.

      Car EX182/38 - Engine EX182/43

      Car EX182/39 - Engine EX182/42

      Car EX182/40 - Engine EX182/44
#P - LBL304 - Practice car
      Car EX182/41 - Engine EX182/45

In June 1958 another car bearing the registration LBL304 and carrying the chassis number EX 182/41 appeared. The build sheet still exists, and shows that a new Twin Cam chassis was used, together with an aluminum body. This was a completely new aluminum body (6 were originally produced) on a new low Twin Cam chassis, so not a lot in common with the original EX182/41, except that it was a factory produced reincarnation under the same factory EX program.

EX 182/41 - fitted with new Twin Cam chassis, engine and wheels, low light front end (similar to LBL301 at Dunrod), now registered as LBL304.

Factory developments next project was the special bodied Twin Cam EX 186.

Addendum August 2007:
There is now considerable evidence that the car shown above, participating in the 1958 Gaisberg Hillclimb, etc, may actually have been EX182-40 (rather than 41), and that this car was later to be reconstructed again to become SRX 210.

Dundrod 1955 photo by mechanic confirms that the works aerodynamic body raced only once, was wrecked here.
