My mate Peter who already "sculpted" some vehicles and guns for Hagen and Blackwatch.
Now Peter started his official shop. So if you want to have your own special product, simply write him and he can fulfill your wishes if he has enough information on it.
And if you don't want a 3d-printed model, but in metal we could cast it.
Just to show you Peters last work for Blackwatch - French artillery ammunition and equipment wagons.
