This is a brand new N Gauge Class 15 Locomotive shell in resin by Parkwod Models, to fit a Graham Farish old type Class 20 chassis (not supplied), one of the photos show a completed model and another darkened to show detail. Sale is for a new unused shell with instructions. It is possible to fit the body upon the later type chassis as the last photo shows with a class 15, but it involves work on the chassis. Thanks for looking.
