To: Hs.{Lord Ernest Hives - Chair} From: G.W.H. Hôtel de France, Châteauroux, Indre. REPORT ON 18-EX 10.000 MILES CENTRAL LUBRICATION. We have taken off the body and wings to make a thorough examination of the chassis. All Bijur drip plugs have been tested in their respective positions under the worst conditions, i.e. dead cold. All bearings have been examined for state of lubrication. We give the original drips per min. of the Bijur drip plugs (taken under normal temperature conditions), condition of bearing surfaces as found. Bijur drip plugs that appear to be choked have been examined. We give a sketch showing how this is done. Will you please have blue prints made and attached to report. Bijur supplying unit. Drops per min. As fitted Condition of bearings. Road springs. Front Near side rear. 2 4 Well lubricated, bearing and pin worn, pin loose endways. Near side front. 2 4 Dumb iron pin well lubricated.
