Coverley - Production Engineer} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}5/MA. 7.11.32. x PEREGRINE CYLINDER HEADS. We are getting somewhat involved with the Peregrine Cylinder Heads owing to the various compression ratios, valve sizes and turbulent and non-turbulent types. It would be of great assistance to us if you could fix a plate to each head giving the capacity in C.C's turbulent or non-turbulent type, large or small dia. valve. If in addition each head had a number we could keep track of the various modifications made to it. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
