Aluminium Alloy Rims for Wheels. ROY {Sir Henry Royce} 4/MG. 21.1.35. It is very easy to give these aluminium alloy wheels a run on the bump, which should indicate whether they are hopeless or not. We should therefore like to try a set, which would of course be in our standard size - 5.50 x 18. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} | ||
