Wraith - Side Steering Tube Springs.

Further to our memo BY.8/G 13.5.38, sending you half a dozen springs produced in Chrome Vanadium Steel, by J.B.Skinner & Co. Sheffield, we are handing you herewith six further springs produced in High Carbon Steel by the Tempered Spring Co.

Will you please carry out similar tests with these springs, to those you did with the chrome vanadium springs.
