From what I know there are also a couple that are made in a sort of wood finish type of colour. Don't remember exactly, but these had a specific name how they were done/how they were finished, I just know Pauls brother auctioned 3 in a row. Was trying to get one but it just stopped after 3
And than there is also the bronze (real bronze not painted) version, dunno how many, but I wouldnot mind owning that one.
