I was beating the leaking batteries out of mine last week. I was thinking that it would make a great host for a SSC P7 or Cree MC-E since it's SO HEAVY. It's not in the best shape, but there is plenty of AL there to send it to a machinist to have it turned down ans anodized (remove the rubber grip). Maybe you would be interested in working with it?
EDIT: You can have it, I don't need another project
I've got two sets of Nexstars (2C, 2AA, 1AA) but at the moment I can only find both 2C and both 2AA. Sent me a PM with your address and I'll ship whichever ones you want this Saturday. They're all in as-new condition.
