X4429 ROAD SPRINGS. ----------- I think it is important in discussing the merits of different types of road springs produced by different makers that we should have the history of all the springs delivered for that particular job, otherwise wrong impressions are apt to be made. My impression in regard to the position of the Peregrine is that Firths springs varied between 60 and 80 hours whilst Woodheads were between 30 and 60. BY | ||
