Well, I went down a rbbit hole with this thing last night. I knew Hasegawa had released an Aleutian Tiger version of this kit, and lo and behold, the shrouds are present on the sprue next to the exhaust pipes, so no need to scratch them, which is nice. Thanks for pointing that out, or else mine wouldn't have them. And every pic I can see has them in place.
The second piece was that apparently the Hasegawa Aleutian Tiger kit supplied different gun plugs for the wings, without the protruding barrels for a very early -E variant. Mine, however, has the protruding barrels.
After much searching of actual photos, it appears that both versions were used by the Aleutian Tigers. I have a theory that the first planes in service with the unit did NOT have the protruding gun barrels, and I have yet to see one with the star-no-bar markings that has protruding gun barrels.
However, my decals have the star and bar with the red outline, and photos I have seen of the planes with these markings DO, in fact, have protruding gun barrels, so I am comfortable leaving them on, which is always nice.
Again, I am building the one in the foreground of the photo below, and while I don't have an image of the guns, the plane in the background appears to have exposed gun barrels. It's possible that the black marks on the leading edge are gunpowder residue, but I really doubt it, as you just don't see it that much in actual photographs.
The image below lends credence to my theory, I believe, that replacement planes around the time the red outlined star andbar was introduced had the exposed gun barrels. It also appears that the front part of the exhaust shrouding was always there, but the layers over the middle part weren't necessarily present. This one is clearly an Aleutian Tiger, as evidenced by the winterization and the plane in the background with the tiger on it, but it hasn't had its tiger painted on yet. It also shows that the spinner and tiger weren't painted at the same time, so it's possible that there would be a variation in the color between the two, which is good news for modelers going crazy trying to match it.
Thanks agin for the heads-up!
