Having obtained this information, what further reduction could be achieved in material, due to buying in quantities, and labour; due to reduction in man hours, if the Park Ward construction was adhered to and tools could be put in hand the cost of which could be spread over 6,000 bodies to flow through the shops on conveyors at the rate of 60 per week. What advantage from the improved plant and larger quantities would accrue to coupe bodies at the rate of five per week and the other custom built bodies in the pre war quantities produced by Park Wards. By the time these figures are available, the P.S.C. should have produced their estimate for a shell and its tool cost. Generally speaking the shell cost is less than one quarter of the total, the rest of the cost being common to both types of body. Hence seventy five percent of the cost estimates on the P.W. body will be applicable to the P.S.C. body. When we have these figures we can undoubtedly find out in detail as we have done on the chassis, how they compare with what other people are doing and this should suggest further economies.
