Brabham BT45

I took this photograph at the Donington  Park Museum in October 1989.

I've labelled the car as a 1978 Brabham-Alfa Romeo BT45, and presumably this is the identification placed on it in the museum. If it's a 1978 car, however, it should be a BT45C, but that car had a different nose to the one in this photograph. The BT45 (the 1976 car) and the BT45B (the 1977 car) looked like the car here, though photographs of the BT45B show it with different markings on the rear aerofoil, so the BT45 label is possibly correct.
