| 1370 BY/NO. c. BY/ORB. c. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} BY.4/G.24.5.39. BENTLEY V.{VIENNA} WIRE WHEELS. I have arranged with the Dunlop Co. that we shall use the loose balance weight secured to the outer diameter of the rim on the inside of the wheel by a spring clip, the tyre bead pressing against the spring clip to retain the weight. I have arranged with the Dunlop Co. to make a 72 spoke wheel now that the balance weights on the inside of the rim have been washed out. Will you kindly arrange to modify the drawings and send on copies to the Dunlop Co. BY.{R.W. Bailey - Chief Engineer} | ||
