in your worklist thread I have some more references, the ones you have now IMO do not credit as too accurate (well the 3D render is but fit it together with there others. even on your reference, the gun is shown in the middle of the magazine.
I did look at them a bit fast to... but as I see on them I have only drawn the gun hoist and the forward part of the magazine, I miss the other part of it, where the 4-leveled pallet hoist is.
The reason for why the drawing become like that is that I had to a middle thing between all those drawings.
two of the drawings, and a 3D view I found (Can't find it now. yeah! funny that, when needed...) give me the basic of what deck position they was on. compared to the size of the "Old" gun-house drawing (That I have a bad feeling about it's perhaps to big!), where some approx where the gun-hoist is placed, but also approx size of the magazine (at least, half of it!). then I had the references to help me with basic looks. but I did dropped many details (to my standards: weird!!).
I come with an new update, tomorrow. I hope!
Lets do the: I update, you comment, I adjust, you comment some more.... In the end we will manage to get it as close as we can get it with the limited references we have!
