BENTLEY III BONNET In view of the cost saving which is obtainable with a steel bonnet over an aluminium one and since this type of bonnet will be used on Bentley 50, will you please scheme the Bentley III. scheme for .036" (20.SWG.) steel, instead of .064" aluminium as previously requested. This will give us a weight increase of approximately 4 lbs. and will save approx. £1. 15. 0. Rm{William Robotham - Chief Engineer}/Std. | ||
