Herewith W.W. scheme for fitting Chrysler type balance weights. Will you please, therefore, machine the crankshaft in IV-G6 to this scheme i.e. webs 1, 6, 7 and 12 to Sch.1402 and the remainder to this LeC. We will let you have later details of the size of the 1/2 weights and also details of small dummy weights to keep the crankshaft in balance when these weights are not in use. We think that the studs for the half weight might be made and locked as on Sch.1402.
