| X 308 To BY.{R.W. Bailey - Chief Engineer} Copy to Hs.{Lord Ernest Hives - Chair} RND. E/PSN.1/MN.18.6.35. SPECTRECodename for Phantom III CARBURETTERS. We send you herewith LeC 4548 showing modified throttle return spring mountings for the above carburettors. The four springs and links are now the same, those on the rear carburettors being fastened to the throttle shaft coupling and those on the front carburettors to two short levers. One of the front spring anchorages has had to be modified to suit the new top water pipes. It should be noted that this scheme modifies LeC 4495 and LeC 4537. E/PSN. Att: LeC.4548. | ||
