A vacuum shop here has all the kirby models made. He had all the gold kirbys on display once. My friend bought the Gold tradition he had from him. It was unused but the gold was flaking off so the store had it sent to some place in town that does the plating and it has some special permanent gold coat. Cost him $600 for the plating I guess!
I think the Tradition was the best looking gold kirby. The other ones they kind of just slapped together using part from the standard models, but the tradition had its own unique pieces, even the bag!
