Here are some scale model Foreign Legion forts a la Zinderneuf.
Modular 3D Printed. This one appeared on Facebook and it’s really well done but I’m can’t find the original post. It appears in some large wargame tables so I’m thinking it is available as a 3D .Stl file somewhere. If anyone can point me in the right direction I’ll be sure to provide attribution.
Colonial Steamboat Company. These guys make really nice scratch build terrain including nice Afghan hill forts and, of course steamboats. This is a representation of several Legion forts that I’ve seen from them.
Airfix Mod. Not sure where this appeared–probably Facebook. Nice job converting the old Airfix fort into something much better than the out-of-the-box configuration.
Small Scale. This is a nicely painted model for smaller scale figures I’m guessing 10mm or 15mm. Again, I probably found the pictures on Facebook. It’s hard to tell if it was scratch built or from a model as there seems to be many add-ons to make the scene.
