Would you kindly ask whether Mr. Whyman can let us have a dimensioned sketch of the exhaust silencer we have to put on Ripplet, as promised to us by Rm.{William Robotham - Chief Engineer} at the conference last Tuesday week. The model is on Ripplet. We need this badly. Ev.{Ivan Evernden - coachwork} | ||
