Just to add some more information supplied to me on the photographs.
Following Robert's observation, the guage must be oil pressure. The air pump was slung under the dash, the later TT cars having it sited externally on the mechanic's side.
The air pump is connected both to the fuel tank and a 0-5 psi air gauge. Running pressure is 1 psi and when the engine is not running the pressure needs to be released. Under pressure, heat, eg sunlight, etc, can cause burst joints.
The spare wheel was situated in the tail.
In the second photo, an inlet and blow off valve can just be seen, so the engine is supercharged which suggests Chris K-C's assertion is correct.
