| To ROY {Sir Henry Royce} /GEA. from Hs {Lord Ernest Hives - Chair} /Rn. {Mr Robinson} L4308 Hs {Lord Ernest Hives - Chair} /Rn {Mr Robinson} 3/LG10.1.29. X4665 With reference to ROY {Sir Henry Royce} /GEA9/EB9.1.29. While our tests have proved that the Jaeger speedometer functions fairly well, we should be very loath to standardise it in place of the A.T. We have pointed out to Sales however that there is no objection to them being fitted to cars if specifically demanded by the customer. Hs {Lord Ernest Hives - Chair} /Rn. {Mr Robinson} | ||
