X4050 X4299 The following is extract from the Minutes of the last Sales Conference:- "It was decided to ask the Works how much bigger a straight-sided tyre is than a beaded-edged tyre, and what is the equivalent of this in terms of teeth in the back axle pinion, so that we may decide the effect this will have on the 14-tooth axle." Will you kindly let us know. C. [STAMP] RECEIVED 25 JAN 1922 PS | ||
