To E.{Mr Elliott - Chief Engineer} from Sg.{Arthur F. Sidgreaves - MD} Sg{Arthur F. Sidgreaves - MD}2/H16.4.34 - 2 - on the bench and checked up for vibrations etc. with the 20/25 to see whether it is really correct that the engine mounting is the chief reason for silence, smoothness, absence of vibration etc. in the car. There seems to be a good deal in the American saying that a pound of rubber is worth a ton of theory! Sg.{Arthur F. Sidgreaves - MD} | ||
