Hey mate. I had three there but in need to keep two. The other one I noticed has a small crack in the beryllium so I’ve bagged it up for the bin as sonically it’s stuffed and highly toxic,

sorry mate would have loved to help out 

[Bunno77]

Thank you very much anyway. I appreciate the effort.

Have you considered yahoo/Japan?

Problem will be shipping back to AU as there are postal restrictions on spkrs/drivers. Couriers will be expensive. If you are not in a rush then if you buy through import monster then container shipping would bring the freight costs (way) down.

That's no problem as the actual cone is polypropylene that's coated with Beryllium powder. I made the big mistake way back 90's of cleaning the corrosion on the Beryllium with a cotton bud and metho and it wiped away only to leave the see through polyprop cone under it.

 All you have to do is dismantle it using a mask and surgical gloves and use a smear of 24hr Araldite on the back of the polyprop cone crack to seal it, and re-assemble it.

(Only the NSX 10000 and the GF-1's had pure Beryllium cones)

It’s all yours George. You just need to collect it from the land fill in Frankston

To be fair this one had suffered a catastrophic injury while in the garage. I wouldn’t have felt comfortable selling or giving it away. 
It was well and truly ready for the bin.
