Hello Bill!
Well, I'm always glad if I can help!
OK, in case of Part 44, 45 and many other, similar parts - the way of building them is detailed in the instructions in rys. 4 (drawing no. 4) - right under the bow of the general plan of the ship. The tricky part is to understand that you fold the part to form a kind of a box with the colour on the insides. I'll add here that I'm not a fan of those glue tabs - I routinely cut them off and replace with a piece of scrap leftover material.
Now if you look at the two triangular portions of Part 44 - they are to be horizontal, the lower one will have its colour, printed side pointing up, and the upper one will have its colour side pointing down. The round "cutouts" of those triangular parts is where the round gun turret (Parts 36-43) goes. If you dont glue the turret subassembly (Parts 36-43) to Part 44, you will have the option to traverse the casemate guns! That long, rectangular strip of part 44 (the wider one) goes around the turret subassembly with its printed side toward the turret, to hold it in place. The narrow and long rectangle of Part 44 is supposed ot be vertical and parallel to the side of the ship with its printed colour side facing to the outboards.
And once you figure out Part 44, you'll already know how to do parts 45, 46, 47 , 48, 49 and 52.
Now I hope I explained it so that you can understand it... If not - I'm going to have to print out one of those and fold it and then post a photo!
Good luck with your paper warship and have a nice day
