every time I see a tiger, they always had the smoke canisters on them, unless its the early versions, but yes I have wondered the same thing, now that you think about it why don't we have them in AH? It would bee cool. FYI im talking about the smoke canisters on the side of the turret.
EDIT: here is some info on it from wiki: "In May the addition of mudguards bolted onto the side of the preproduction run, while removable mudguards saw full incorporation in September. Smoke discharge canisters, three on each side of the turret, were added in August 1942. In the following years similar changes and updates were added, amongst which the addition of Zimmerit in late 1943.''
