Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} From. G.W.H. B. 56. BN.{W.O. Bentley / Mr Barrington} - BENTLEY. Third Test Carried Out with New Needles. Petrol Consumption with L.B.2 Needles was 12.52 MPG. Petrol Consumption taken over a distance of 194 Miles. L.B.2 Needles 12.52 MPG. Average Speed..... 59.4 MPH. L.B.2 Needles Maximum Speed 100 MPH & 99 Inwards Outwards. L.B.3 Needles. 12.56 MPG. Average Speed..... 59.54 MPH. L.B.3 Needles Maximum Speed 99 MPH & 98. The L.B.3 Needles are definately down in acceleration from 30 MPH. on to-day's running. Road conditions identical with previous tests. The Barometer however has fallen and is low to-day. We consider from our tests that the L.B.1 Needle is the best allround. ------------ G.W.Hancock G.W.H. | ||
