Bailey - Chief Engineer} c. to Da. {Bernard Day - Chassis Design} Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} .1/AP.11.1.37. WRAITH BRAKE SHOES. With reference to our memo Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} 1/JH.4.1.37. we have received a letter from the Bifurcated & Tubular Rivet Co. and in order to use this type of rivet on Wraith brake shoes the only design alteration necessary is the addition of flat platforms to receive the rivet tails on the taper side of the outer flange. These can be copied off 20-25.HP. RRC. will have to buy a new anvil. Will you please arrange with By. {R.W. Bailey - Chief Engineer} to have the details altered.
