In order to get further data on B-10 unit which is not runnable because of the new clutch to N.Sch.4190, we should like to fit the flywheel and clutch that is at present on the supercharged unit B-12, with the back plate of the flywheel thinned as per the attached sketch. Will you please fit to B-12 unit a standard flywheel and clutch. We think we should have several of these taken off engines when disc flywheels have been fitted.
