BY/FWH [Strikethrough] c. Hs.{Lord Ernest Hives - Chair} 15360 BY15/H.{Arthur M. Hanbury - Head Complaints} 7.8.25. 15360 [Strikethrough] 18360 [Strikethrough] 20 HP & 40/50 HP. CHASSIS. REAR BRAKE DRUM COVER. I am handing you herewith N.Scheme 2038 and 2039 showing proposals which have been put forward to overcome the complaint which we have from customers in regard to small stones getting between the cover and the brake drum itself, setting up a squawking noise which is most disagreeable. Will you kindly detail the two schemes and issue them experimentally only. BY.{R.W. Bailey - Chief Engineer} | ||
