Hez--another great idea, too bad it didn't fly.
Darkside--Dave Sciacca is probably still offering his brass castings, maybe start a new thread asking for info. if you don't find it w/ a Google search?
Many replicas of varying degrees of accuracy have been done. IMO the best to date will be Chen's run of machined replicas, which although delayed should be being received soon. See the thread which is still up.
All--please see my post above for updated picture credits.
