| HS.{Lord Ernest Hives - Chair} FROM HDY.{William Hardy} ORIGINAL. C.c. to B. DY.{F R Danby} REVERSE GEAR - 20/25. HDY{William Hardy}2/M22.8.32. X5310. With reference to the favourable report - HS{Lord Ernest Hives - Chair}/GRY{Shadwell Grylls}2/KT12832. - on the reverse shaft to N. scheme 3492, we should like to know whether any variation of the travel of the shaft was made to ascertain the value of the increased overlap of the gears. If not, would you kindly try the effect of a travel of .950 instead of 1.100 given on our drawing. GRY{Shadwell Grylls} HDY.{William Hardy} | ||
