Found it on Craislist today for 60 bucks not too bad needs some work, the lid has a big ding in it but the bottom bowl is in really nice shape but it is pretty cool looking!!
ok...these pics aren't the best, but on short notice, I think you can sort of see how it works.
You can kinda see in the last pic how the lid handle rests on the holder of the side of the cart. Then the lid almost half tucks under the open area of the cart itself
