Your research is somewhat mis-leading.
The Aust. book for Carriers, M.G., 2 pdr, and 3" mortar, says short side to the front.(on the ground) HOWEVER, the same paragraph also states that the NZ carrier tracks are fitted the opposite way.
The Canadian book, UC-F1 Describes fitting as("top run over the guide roller") Double lug to the front. (short side forward at the top)This is the opposite, to the Australian way of fitting the track.
It might be a good idea for Andrew to refer to a T16 manual.
My research indicates that you have a 50 percent chance of being correct.
( that is unless there is a third way to fit them)
Who knows if one way increases track life, or possibly better traction.
I remain open minded and polite. ( I might need an instrument cluster done in the future)
The Brit.Carrier manual (Chilwell No.63/63) describes fitting as per the Candian book; Double lug to the front over the return roller.
So to sum up. Canada, U.K. and N.Z fitted track the opposite way to Australia.
Time for David to give us details on the T 16.
