| X5010 By: Hs{Lord Ernest Hives - Chair}/Gry.{Shadwell Grylls}9/KW.30.5.34. Overhanging Balance Weights - 20/25, LeC.3758. We have run a set of these 10,000 miles on GLN-60, held on by one stud only. Those to the LeC. are running on 21-G.IV. Frequently in the past we have run overhanging weights without trouble. We see no reason therefore why weights to LeC.3758 should not be fitted to the 20/25. They are required to restore the original amount of balance.
