For it's time, the model isn't bad, but the highlight for me is the shunting pole - that black plastic piece with a hook on one end and a spade on the other. As a device for operating tension-lock couplings, it works surprisingly well. At least the spade end does, I never have much luck with the hook. In a perfect world, the handle would be longer, but then it wouldn't fit in the box.
Over 80,000 examples were made, so this isn't a rare collectable. Being complete with the pole adds value though, as many of these would be lost in play. Not a huge problem, as alternatives have always been available.
