X3725 X8810 You will recollect that on the 3rd. of May 1929, we ordered a pair of 21" rims from the Dunlop Co., having the rim moved outwards .50" in relation to the hub. We now require a set of six 5" x 20" wheels altered in the same way so that the effective track of the car is increased 1.00". Attached is the drawing of the standard 20" 40/50 wheel shewing where we wish the new tyre centre-line to be. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
