Some German vehicles at Green Valley in 1967.
The Porsche 356 Speedsters had various issues such as ;
Losing a left front wheel as a TR 4 # 11 passes by.
Number 15 trying really hard;
Before destroying his left front going off the circuit.
Other Porsche stayed on the circuit.
Even one was brave enough to enter the track as a McLaren M1B flashes by.
With something amiss with the tail pipe.
