Hi,
This is the driver's hatch. As per Squadron M113 walk around, the hatch has four M17 periscopes on the sides and one M19 on top.
Below are the parts provided with the kit, the basics are there but there is a lot missing. For some unknown reason, Ludwigs seems to have 2 versions of this roof section. This one and another one shown in the instructions with wider periscope holes and engine grille. The one I have needs correction in order to be more accurate.

I disregarded my earlier plans to use Shapeways King Tiger periscopes. The M17 periscope is much wider and size matters in order to represent the hatch section correctly. The first task is to fill the pre-cut periscope holes because they are not located at the right place and are not of the right size.

The hatch hole itself is too much on the left when viewed from the back. It needs to be moved to the right, closer to the engine grille as shown. The 3 rings are glued together and once in place, the hole is trimmed as per revised hatch tunnel location.

New 13mm wide periscopes were created out of plasticard. References show the M17 periscope to be quite flat and as such are easy to reproduce. Periscope guard are made of Photo etched fret left overs. The M19 periscope vocer was built with the help of a Sherman 1/35 road wheel, emptied, with a plasticard part added on top and then trimmed on front and back, then placed on a thin plasticard round piece. Now that I look at it in pictures on large screen, I can see a few things that can be improved.

I tried to reproduce the production hatch hinge arrangement as best as a could, reusing some parts provided by the kit, the rest is hand made from plasticard and a simple brass rod. This was quite fun to do.

That third bracket on the right attached to the hatch is not provided in the kit and needs to be scratch built.

The hatch can be opened of course. I am planning to show a driver. However, I have not yet finished the interior of the hatch. I am still searching for a good picture showing the location of the handle and of the locking mechanism in order to reproduce them. The hatch will be left open. I have not seen any reference picture of M113 in storage or in the field with the M19 periscope installed.

I can see superglue residue that needs to be cleaned up. The 3 rings had to be filed a long time to end up with a smooth surface. This is one area that will need pre-painting and thorough checking to ensure no cracks or misalignments are left between them. Its hard to see cracks within all that white stuff.
