Your drawings and QWTs are superb! It’s exciting to see the detail on your QWT’s.
Yes, all rear wall doors, spent shell ejector scuttles, access plates, etc. are curved and follow the curvature of the mount’s wall. When closed, they do stand out from the wall, varying from about 1/8" to 1/4" (3-5 mm), enough to be noticeable even in small scales. The variation is clearly what one would expect as a normal part of WWII-era steel mass construction.
If you need more ship plans for this and other projects, we offer more than 200 for free download. Most are US Navy general arrangement drawings but there are some construction drawings, too. Link:
Below are a few photos of how the doors, hatches, access plates, etc., print in 1/200 and 1/128 scales integrated with the gunhouse so in 1/48 they should look really good.
Interestingly, when Trumpeter released their 1/200 scale USS Missouri BB-63 and USS Iowa BB-61 kits, they included the wrong 5" mounts. The Trumpeter kits have cruiser 5" mounts, Mk.32s which have a different shape. Once you see them on those kits, you can’t unsee them.
Very Fire made a similar mistake with their new 1/350 scale USS Atlanta CL-51 kit. Instead of the heavy Mk.28 mounts they should have included, Very Fire included lighter Mk.32s, duplicating the same sprue from their Cleveland class cruiser kit. Again, once you see it, you can’t unsee it. Later Atlanta cruisers of the Oakland subclass did have lighter Mk.32s, installed to help reduce stability problems of the class (the ships were top-heavy). But the early ships of the class did not. The early ships had Mk.28 mounts or a mark that had the shape of the Mk.28.
Cheers!
