Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} DA{Bernard Day - Chassis Design} EXHAUST SILENCERS- P. 2. & 'U' SERIES 25HP. We agree that P. 2. short silencer should be used, but we think this can be made equally good by spot welding instead of riveting, so saving much in labour cost. P. 2. must have a silencer, probably 8" dia., that will not absorb so much of the BHP. at full speed of 3000 RPM. EV.{Ivan Evernden - coachwork} is sending a drawing. R.{Sir Henry Royce} | ||
