Alguém do Model Warships esteve esses dias no Belfast e mediu as chaminés com a ajuda da tripulação. A conclusão que chegou é que a chaminé de trás é uns poucos centímetros maior no sentido longitudinal que a da frente.
"Well I spent a happy couple of hours on and around Belfast today looking at these funnels.
They are the very devil to assess by eye - because of their teardrop shape I think. Take a photo from slightly forward and the forward funnel can look bigger, take a photo from slightly aft and the aft funnel looks bigger. It is impossible to take an absolutely broadside-on photo of her from the sort of distance which you would need to to get a true impression. The closest you can get to a broadside view is from the north bank of the Thames, but because the Thameside path is closed there for some building works, even a photo from there is taken from slightly forward of the midpoint between the funnels - you are still seeing slightly more of the aft funnel - and, as I said, I dont think its far enough away in any case.
However with the help of one of the "crew" I was able to measure the funnels by running a piece of string around their bases (just above the "skirt" at their base). In "circumference" the aft funnel is 7.5 inches fatter than the forward funnel. So that is 3.75 inches more on each side, which IF shared equally between length and width (fair starter I think since we are talking about a curve through 180 degrees, means broadside-on the aft funnel would be 1.875 inch (4cm) longer fore-and -aft which I think would be pretty indistinguishable in 1/350th scale (as part of a side face that measures 22.5 ft horizontally).
I have a suspicion that the funnels are a very slightly different shape, the aft one being perhaps bit fatter/flat fronted so the "extra" may in fact all be in width not length. The funnels are constructed from a series of panels riveted on to a framework. I have taken a series of detailed photos of these panels all the way round both funnels and it may be possible (by counting the rivets!) to assess exactly where the extra 3.75 inches is on the aft funnel. But that is for the weekend!
Otherwise you need a proper set of surveying tools to measure the fore-and-aft dimension of each funnel as its impossible to accurately judge what is square-on to it by eye given how near-identical in size they are, how close to them you are up on the deckhouses, and all the things that get in the way!
Hope this makes sense. I'll post some photos when I have resized them to suit this site's requirements- and perhaps counted the rivets!"

Porém contando os rebites (acreditem, foi assim mesmo), chegou a conclusão que ela deve ser um pouco mais arredondada que a da frente, que é bastante elíptica. Isso dá a ela um maior volume, que em determinados ângulos faz parecer que ela é maior que a da frente.
The rivet count is done. From the forward end of the forward funnel the number of rivets along the bottom of each panel both sides are 18, 18, 18, 19, 18, 14, 5 and 10. On the aft funnel there are 20, 20, 20, 20, 20, 13, 6 and then 10 to port but only 9 to starboard (the aftmost panel wraps around the aft end of the aft funnel to the starboard side). So the rivet count tallies with my measurement that the aft funnel is bigger in circumference.
Although I suspected the funnels to be subtly different shapes, it had not occurred to me that one might be wider than the other! If someone had suggested that then I think my eye would have said the aft funnel was wider - but they are so deceptive. Next time I go back I will try to go equipped to take accurate measurements of the funnels both fore and aft and athwartships.
However, having now reviewed the photos I took from the north bank whilst dodging the site security men I think I did after all manage to take one useful one from exactly broadside midway between the funnels. If you put a ruler on the photo the forward funnel does seem to be very slightly “narrower” than the aft funnel.

O fato é que de qualquer forma a Trumpeter exagerou a diferença entre elas e que os sets de correção que estão sendo desenvolvidos (Flyhawk e White Ensign) provavelmente resolverão o problema.
