| HS.{Lord Ernest Hives - Chair} FROM DA.{Bernard Day - Chassis Design} ORIGINAL P. 2. GEARBOX. We notice that in the case of the sliding gears for the 1st. and 2nd. speeds the 25HP. has the boss flush with the teeth, while in the P. 2 the boss overhangs the teeth by approximately .150". As this is lengthening the box we should be glad to know if we could have P. 2. flush like the 25HP. Could you test this forthwith as we will embody it in the new box if it is found to be alright.
