| Y4630 W.O.R. from Hs.{Lord Ernest Hives - Chair} Hsl/LG29.2.24. CAMBRIDGE LABORATORY CHRONOGRAPH. We wish to place on order with the Cambridge Instrument Co. a Laboratory Chronograph with special tenth second contact breaker. The cost of this instrument is £60. O.{Mr Oldham} O.{Mr Oldham} This instrument will enable us to obtain very accurate braking, acceleration and tractive resistance measurements. With the method we use at present to obtain accurate results, it is a laborious job to obtain tests on braking frequently, we soon can wear out a set of tyres. The cost of this instrument will very quickly be saved on our tyre bill. Rg.{Mr Rowledge} is in agreement that this instrument is very necessary for us to have. Hs.{Lord Ernest Hives - Chair} | ||
