This model is based on the type of field artillery used by the British and allied forces at the battle of Waterloo. You are free to use the model in any way.
The download includes a high poly and a low poly version of the model. Both work well in unreal engine - use the HP version for UE5 with nanites enabled - see image below.
Click download and select original format. Unzip the file once downloaded and open the source folder. Unzip the file in here and you should have both fbx files for the model.

Import into UE4/5 with a global scale of about 500 - tick combine mesh - HP version works well in UE5 with nanites enabled. Metalic materials will need a constant set at 1.0 plugged into the metallic connection and a constant of about 0.2 into roughness.
