B 312 APRIL.2.37. Mr. Cogswell. Re G.83341. "Cadmium Plate where marked 'C'", has now been added to this piece. The distortion found in the ball race dia was caused by screw-milling after grinding. The ball race dia is now ground after screw-milling so that distortion should not now occur. f.{Mr Friese} Kershaw. | ||
