Sym. 606 Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} 15/MH. {M. Huckerby} 1.9.37. WRAITH HAND BRAKE. We have had complaints that Wraith Hand Brake is too rigid, and want to try scheme G.C0.45, which is 3 times as spongy in the shaft. Will you please make one such shaft; it can be fitted to the first Wraith to go into the shop, when ready. Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} | ||
