This was brought recently from a fellow forum member for a good price. This engine has never been run or with the look of things been out of the box, It is in lovely condition. For the keen eyes amongst you will notice this is no normal T90, as the base and fire box is different. This particular T 90 was developed for use in schools to demonstrate how a modern power station works, and the transference of energy. So a very nice twist on a very nice engine.
