This is a resin detail parts set for use with military vehicle kits.
From the manufacturer:
Fountains like this are found in their thousands across Europe and can be added to every building in this range to extend scenes and dioramas futher. Adding this to a road scene using Airfix vehicles makes for something different. This model can also be a perfect addition to model railway layouts.
Measures 100mm x 100mm with a 30mm height. This is an unpainted resin model.
