I've just re-instated this model, even though the Shapeways cost increase had added to the price.
Requested by an O-scale modeller, and based on my N-scale woodchip trailer. As requested, I've not modelled the wheels/axles, so the customer can choose their favourite make/style to fit the chassis. I've modelled small pilot holes for the axles to aid assembly. This is a massive model, over 13" long !!
