| BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} GRY{Shadwell Grylls} x simo DA{Bernard Day - Chassis Design}1/M8.3.33. C. to SG.{Arthur F. Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} ES. E.{Mr Elliott - Chief Engineer} HDY.{William Hardy} J.{Mr Johnson W.M.} 3. FRONT AXLE. With further reference to increasing the pivot lean on the J.{Mr Johnson W.M.} 3. front axle to 4° from the vertical, we send a further drawing, N. sch. 3704., which is to take the place of N. sch. 3690. previously sent you. We have shewn 3 bolts instead of 2 on the bottom cover, and have also made one or two other modifications. The result has been to push the brake carrier plate .1 further from the wheel, which we think is of no importance. DA.{Bernard Day - Chassis Design} | ||
