Bentley / Mr Barrington} Bentley. We were satisfied from our tests that the L.B.1 needle gave the most satisfactory results for acceleration, maximum speed, slow running. The L.B.2 was slightly inferior in acceleration. Our tests were taken over a route of 10 miles in length, practically dead flat, and after two days' trial with each needle, L.B.1. gave the most consistent results.
