Just received a pair of 4 wheel coaches courtesy of flea bay. The under frame is wood and the bodies are plastic. Wheels appear to be "O"gauge.The coaches have a door at each end and the glazing,seats interior slide out,which will make it easy to repaint. I intend to fit the bodies on a pair of Skip frame chassis as the w/b is about the same,new end overlays and interiors. Doors will be positioned on the sides. Gives me something to do.
