Excellent builds going on here.... Am looking forward to seeing the painted versions, especially the UN white. I would think that would be a tough one to pull off, so I am looking forward to seeing how it is tackled.
Just some more details on my little BARV out of the way......

Now these --- I had to build 3 of them --- surprised me. I was expecting a real hassle with them, but once the basic idea hit they went together fine. At this rate, I might even have to give this white stuff another try one of these days.
In case you are wondering about the upper window blue.... it is a mistake. I cut the windows to tall, but as the blue ends up almost flush to the outer wall of the cabin I just made the window surrounds the right size and will paint over the upper blue areas. They are also hidden by the overhang on the roof... a lucky save.....

Had considered doing the escape hatches as raised 5 thou shapes, but decided to give scribing them a try. Made a template to guide the pointed scriber and then finished off with a Mission Models Micro Chisel with a scribing blade. Worked nicely, and the outline of the hatches are flat channels rather than V shaped lines.
The amount of brass work on this cabin surprised me. However, it went fairly quickly and the steps came out pretty uniform.... am pretty pleased with that.

I have no idea what the fitting on the side of the nose is, but I figured that if it was there on the real thing I should at least try to put it on the model. Another hand rail and the center tow fitting and the cabin is done...... on to the roof!
