[9W Monighan]

I've always wanted a D9G or H working model. Look at Jerry Hall's wooden models on here. 1/8th would make it much more easy to fit the electrics into. You may need to cover the engine compartment to conceal the electrics,or if it had a cab, that gives you room too.
I don't think one of these 1/12th scale 9's have been built yet from Classic Construction Models. Only a prototype shown here.
