the set is in tidy condition, and all works as it should. i bought it without the chassis, rocks and trucks, but had spares in my collection.
for some reason, the dumper gets stuck at the top of the spiral, so might need to try a different piece of track to see if that helps.
the lid is quite scratched up, so need to see if i can find a polish for it. it also has two "nails" that go through holes in the lid and into the base. means i need to be a bit more careful when opening. there are also numerous spots for the rocks to get dropped and stuck, so will have to use the colored ones
