| B.J. from Hs.{Lord Ernest Hives - Chair} 44886 Hs{Lord Ernest Hives - Chair}2/LG12.1.24. STEEL WHEELS. There has been no std. sheet issued for steel wheels on the 40/50 HP. Neither have we carried out any tests with these wheels on the 40/50. The rims of the 40/50 and 20 HP. are the same but there would be a definite difference in the hubs. If you wish it, we could fix up a 40/50 HP. car with a set of these wheels. Hs.{Lord Ernest Hives - Chair} | ||
