| W/N - Br.{T. E. Bellringer - Repair Manager} X7520 Hs{Lord Ernest Hives - Chair}/Les.1/KW.30.6.34. Controllable Dampers on 2-PY. I have asked Hd.{Mr Hayward/Mr Huddy} to send you 4 grooved pistons for the above chassis. The valve damping disc of these dampers will require reducing from 1.303-1" dia. to 1.293-1" dia. Please note that if the disc is made any smaller the damper will be noisy. We should like to point out that this type of damper has no filter so that cleanliness before reassembling is essential. I should be very interested to hear if these modifications satisfy the customer. Hs{Lord Ernest Hives - Chair}/I.A.Leslie. | ||
