| Re Skefko Ball Bearings. Wor.{Arthur Wormald - General Works Manager} I have just received some 17 boxes of these. A set were fitted to a gear box on 14 Nov-13, or 1926. One of the points we should know is what percentage of bearings had to be returned by the inspectors because they failed to pass the silence test. Mr Matthews is I understand obtaining a report. The bearings used on the bumping test were Hoffman. H | ||
