Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} C. to HS.{Lord Ernest Hives - Chair} BY.{R.W. Bailey - Chief Engineer} JAPAN 3. REAR AXLE AND BRAKES. X.5350. X.5380. Herewith we send N. schs. 3203/4/5 - Rear axle tube, brakes and operation. We have endeavoured to introduce as many economical points as possible. We have not increased the dia. of the brake drums as they seem to compare favourably with P. 2. It seems rather the front brakes that want increasing instead of the back.
