In case anyone is interested:
http://www.ebay.com/itm/111836668915The price is high, but these are rare (this is the first I've seen offered for sale). I have 3 so I won't be bidding.
The usual caveats apply: I have no connection with the seller, cannot vouch for them, do your research before buying etc etc.
The COA is interesting as it gives a bit of history of this tool that never made it into production, despite quite a lot of lead-up marketing from buck .
