Many models I create them from scratch.
Many models are made by great designers and I edit them in order to fit my dioramma needs.
If you are into modding, unreal engine, 3dstudio max, dioramma making or have any relative design needs feel free to download.
Most of my diorammas are over 50MB.
Models based on real models, prototypes, or existing technology and blueprints, mostly within scale.
Good high detailed models if you need to design your own unique pc game or historic documentary dioramma presentations.
