Sorry mate, due to the lack of response i didnt go ahead with it as cost was very high at almost $2000. It is a very intricate design when u pull it apart.
I needed at least 5 people interested to go ahead with it, as this would have brought the cost down to around $1000
I was lucky enough to be offered the one i was going to copy and i bought it.
Good luck in your search as they're hard to find
