Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} E.{Mr Elliott - Chief Engineer} DA.{Bernard Day - Chassis Design} STEERING COLUMN CONTROLS - GUARD RING TYPE. These are at Derby being detailed. They are suitable for J.{Mr Johnson W.M.} 3. and P. 2., with a smaller edition for B. 2., and Peregrine. They are very simple to make, and we think that it is the easiest design that is effective and positively locked. The 4 controls include the dimming switch and electric horn. There is no possibility of trapping one's fingers. The design entails some unskilled work, and one thinks might be made in the Electrical Dept. R | ||
