| X8992. LE CanadelHenry Royce's French residence. Par. Le. Lavandou. (Var) France. Sat. 22.2/1930 For Hives from Dodel. No doubt you will be wondering how things are going with 18 EX. The car is in constant use, average days mileage 70-80. mileage since leaving Derby is 5,350. Car is running very well indeed, body, & wings are receiving a very severe test, as road conditions are terrible. We are obliged to run at 30 lbs tyre pressure all round. No serious trouble has been experienced, Pistons are standing up very well, no knocks hot, or cold. Sparking plugs get plenty of carbon, probably due to extra oil. Oil consumption is v.{VIENNA} good. We are constantly hitting buffer, front, and rear, dampers are O.K. this is due to very large pot-holes. F.{Mr Friese} Dodel, | ||
