| RHC.{R. H. Coverley - Production Engineer} FROM Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} P.1 Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/AT11.7.32. PEREGRINE EXHAUST SYSTEM. This system booms badly. Making use of the existing diameter of section chambers that we have, we think we can quickly get improved results if you will arrange it as per attached sketch. The parts that require making are the adaptor for the front of the silencer, the adaptor for the fishtail at the back, and the fishtail which will be quite satisfactory as a pipe having a flattened end for test purposes.
