That does look like one of the clones of the 166 Assistents from back in the day....
I managed to snatch up one of the original style carts after they released the new version back in the '90s (? I think... I've had it forever now.)
I always liked the older version, so when the new ones came out, I started making some phone calls, and found two of them in New York, at Zelenda who had been importing VW tools since the '50s. They had one with fixed posts and one with the collapsible ones. I ordered the one with collapsible posts, and he even offered me a big discount because he was "trying to clear that version out of his stock"... Yay me... got a call about an hour and a half later, turned out that someone loading the large boxes on the shelves had managed to run a forklift arm through the box, and it punched through the tub... He offered me an even better discount on the other one that he had, and I happily took it. I could honestly say that I bought the last one in the U.S.
Actually, the older version was so popular, that they ended up re-releasing them for a while. I still use mine in the garage at home. It's great for that, but never was quite big enough to roll around at work. Mine is still in great shape, and I wouldn't give it up for anything. Like Travis said, even the used up ones still bring some pretty big bucks. If you are gonna use it, there is nothing wrong with one of the copies... These things are pricey to say the least. When I bought mine, years ago, the retail on the fixed post version like I bought was over $700. I can say that I payed about half, brand new in the box.
