First, let me try again to explain the difference between the T41 and T43. Forget about engines for a moment, or 56/57 suffixes.

The T41 was built in 1956 as a tryout before the new Formula 2 took effect on 1/1/57.
The T43 was the design which went into production for 1957. These cars are easily distinguished from the earlier ones by having more rounded bodywork which incorporated side tanks (not evident in the T41) and a wider and more drooping nose.
Four T41s were built in 1956 (with 56 chassis-number suffixes) and between two and four more in 1957 (with 57 suffixes).
All the T41s were fitted with single-cam engines (1500cc FWB or 1100cc FWA).
Most of the T43s were supplied with twin-cam 1500cc FPF engines, but some had FWA or FWB engines which were more readily available. The FWE was the 1220cc single-cam version used in the Lotus Elite.

On the matter of F2-1-57 and F2-2-57 - neither went to New Zealand. Both were sold in England to New Zealand drivers who, as I said, took them straight to South Africa

OK, thanks very much, some stuff to update and finetune Doug's annexes if he's ever going to produce a reprint
