i pulled it all out to check and found the big loader parts were unstamped, and the very frail instructions listed them as a "building set". it is 100% fake, but 100% identical. rather amazing to think they could get away with it. i brought down the chassis and will pull it to bits later to take comparison photos of a genuine one.
i love finds like this... they dont cost me any money, but still bring the same amount of delight at a new treasure.
