Please receive herewith blueprints of G.CD.307 Modified Position of Interlocking Mechanism for Selector Shafts. All the grooves on the selector shafts are shown milled right across (as on B.lll) replacing the spherical recesses. The position of the interlocking grooves, in relation to the selector grooves, has been changed in order to eliminate the possibility of the selector shafts being weakened by the two grooves being in line. It will, of course, be necessary to modify the plunger housing to suit the new position of the inter-locking grooves. DA. {Bernard Day - Chassis Design} J. {Mr Johnson W.M.} Hardy (handwritten) | ||
