Now let's get on the with the comparison!
As I stated before, the two mess kits are basically the same, with the Swiss kit being much larger. The Norwegian kit is closer in size to the "standard" German mess kit from WW2.
Both of the kits use the unique "two hole" system for extending the handle with a stick.
As far as I know, these are the only two countries that have used this unique handle.
Sweden used a handle that shared the concept of being able to use a stick to extend the handle, but their approach was a bit different. They actually added two D-rings that allowed a much better use of a stick for a handle. The Swedish style is my personal favorite.

Let's take a side-by-side look at the Swiss and Norse kits. The Swiss kit is black. The Norwegian kit is green.
