| - 2 - E/Lid.{A. J. Lidsey}1/HP.10.4.34. (6)- More silent fan - requires more testing. (7)- Hydraulic tappet gear - not in a sufficiently advanced state for production. (8)- Eccentrically mounted dynamo pinion - doubtful if the advantages to production are worth the changeover. (9)- Clutch modifications. Clutch troubles on P.II are not sufficiently numerous to warrant the changeover. CHASSIS. ------- (1)- Harrison radiator matrix - more testing required. (4)- Steering with .940 lead etc. GWH{George W. Hancock - Head Chateauroux} reports on this unfavourably. (5)- Petrol tank - modifications to suit concealed luggage grid - see (11) below. (8)- Exhaust silencer modifications to cure rattles and crackles - more experience and testing required. (11)-Concealed luggage grid - tools for producing this are very costly. (13)-Battery ignition - circular condenser made by the Telegraph Condenser Co - changeover not warranted. (18)-Washer adjustment for rear axle crown wheel. The rear axle on 26-EX is not quiet. This leaves us with few items to recommend for 'T.2' series. These are as follows:- CHASSIS. ------- (2)- Wider front brake shoes - improved braking. (3)- Brake linings fixed with bifurcated rivets - cheaper production.. | ||
