Yellow 5 pointed star transfers - vehicle identification

Came across some information which might be of interest to some people on here:
In February 1943, the 8th Rifle Brigade together with the rest of the 11th Armoured Division seemed destined for north Africa. A large part of their men, vehicles and equipment actually boarded ship - some even left port - before the whole thing was called off. Eventually they would sail for France, more than a year later.

Reading the Battalion's embarkation orders, I came across some notes on the star transfers to be put on the vehicles. I at least never knew when these were first used (not meaning to say this was the first time) and that - at least here - they also could have been yellow (wartime vehicles seen today all seem to have white stars).
