Our version of the German WWII Sentry Box is modeled after one of the various designs used in WW II.
However, the design is fairly common and plain, so it's use could extend beyond the specific intended time frame.
The dimensions work well between 1/32 (54mm) and 1/35 scales, and will look correct with figures and vehicles of both scales.
The kit is laser cut from three types of card and assembles with white glue (PVA). The striped chevron painting can be done before the parts are cut from the card and touched up if necessary after assembly. This particular kit is a good introduction to working with laser cut card model kits.
Besides the example we painted for the sample, many variations can be found in images on the internet and in books. You have some freedom as to colors and weathering of this kit.
