| Steadman +308 E/JNR.{Charles L. Jenner}3/HP.14.12.35. BY c.c. Drg. No. Hs{Lord Ernest Hives - Chair}/Fm. Phantom 3 Duplex Downdraught Carburetter. Please receive herewith:- Lec.4876 showing the water return pipe from the hot spot. Also herewith:- Lec.4877 showing the above pipe connected to the water pump. The drawing shows .625" dia. pipe, but will you please detail this .5" dia. We should like the boss on the pump large enough so that if at any time we have to revert to the large size pipe we shall be alright on the casting. It will be noticed that we have added a boss on the cylinder block to take a clip for the pipe. This would appear necessary as the pipe is long. E/JNR.{Charles L. Jenner} | ||
