| Oy3-E-111226 -3- November 12th, 1926 We found that our front springs on the new axle pad were in some cases stiffened 13%. We made a set of springs which actually had R.{Sir Henry Royce}'s low limit of 30% stiffness when clamped to the axle. The difference in riding with these springs as compared with springs giving 32½% stiffness, was most noticeable. Yours very truly Maurice Olley MO/E | ||
