With reference to BY/EMS/JLO.3.30., we find that the rubber bushes etc., supplied by the Dunlop Co., in the same mixing of rubber as used for the 40/50 HP. engine feet are not to our drawing size. The type of rubber is what we require, but the dimensions must be correct to our drawings. We give below the actual dimensions of one of each type of bush received as compared with our drawing dimensions. PIECE NO. OUTSIDE INSIDE LENGTH. DIAMETER. DIAMETER.
