Yeah, Normand did a great job on that smoker and I know he worked long and hard to get that result. If you want true realism in a tiger tank you would probably be better off just to remove the smoker altogether. The real tanks very, very rarely had smoke coming from the rear, but if they did it should be coming through the muffler and the round plate on the top of the muffler is there to disperse any smoke that it did produce. Remember, the tankers did not want exhaust smoke giving them away to the enemy.
