Draper - Frames}8/SW.16.4.41. MYTH. Radiator. We attach to Rm{William Robotham - Chief Engineer}/HH's copy the original of:- PL.530 Radiator Matrix Mounting & Top Water Tank. PL.531 Radiator Matrix Mounting & Bottom Water Tank. The above schemes shows a proposed size of matrix, of 52 m/m depth, we shall require for the Myth chassis. In design the matrix, yoke, also the top and bottom water tanks are similar to B.V., and these pieces we have assumed will be produced by John Marsdens as the B.V. On the front flanges of the yoke we have provided 'Hank Rivets' for the coachwork section to fix their front blanking-off plate to. With this blanking-off plate fitted, we feel it will not be necessary to have stiffening stays between the yoke sides. Will Rm{William Robotham - Chief Engineer}/EAG. please go ahead with the design of his wing stays in order that we can provide suitable ears at the bottom of the matrix yoke to carry them. We have used the B.V. Water filler cap as it seems quite suitable. The radiator is mounted off the front crossmember on a cantilever bracket by rubbers, similar in design to the B.V.
