These a re 3D printed bodies on a Dapol injection molded chassis. Lots of work to smooth out the 3D printed bodies and not one to take lighthearted as your decals just wont sit down. In the end as there was no surface detail I layered thin coats of paint that sat into the indentations on the plastic until they vanished, Light sanding followed. the white metal hooks and vacuum pipes are from Dart castings. Decals are from Studio Scale Models.
