Assembly
Use this file for how things fit together. It should be fairly easy to figure out. Feel free to ask questions.
There is a downloadable zip file with progress imagery of my wiring if you want that. It includes a rough whiteboard diagram. Check under “Other Files” for it.
Once assembled, paint and age! I'm still waiting to do that last bit.
The author marked this model as their own original creation.
