Your builds are coming along nicely. I have the Tamiya 2A7V, Revell 2A7A1 and Meng 2A8 and following your builds.
The Norwegian 2A8 has extra sensors on the front and rear of the turret that the German 2A8 doesn’t have. These images from the rollout shows the differences. I pointed out the Norwegian sensors in the first two images below. The third photo is the German version. The last photo is also Norwegian.
