This particular Cast Iron engine unit in 29.G.VI. car, B.60 No.2, has now run 4,300 miles on the road, including 60 Laps of full throttle work on Brooklands track, and a considerable amount of over-reving during experimental tests and has stood up very well, in fact we cannot say that all its "thrashing" has had any detrimental effect upon it whatever.
