Who's on guard? Part 1

I could have sworn I had picked up 4 boxes of these, but after opening all 4 boxes one was missing the tower, and 1 contained parts from another set. <sigh>

Base, tower and roof are seperate atm for ease of painting.  I'll build 2 more bases like this for the other 2 so I can build them straight away when they arrive. Also sort out 4 magnetised searchlight mounts / LMG mounts, and discuss with myself if it is smart to add sandbags on top of the roofs.
