But that piece is AWESOME. Good Luck, I'm just a watcher.
I could then buy it and start a new collection of them thar things! Nice one! I wish I had the bucks to spare in order to collect them but my core collection eats up all the spare funds I have (not much here lately).
I can't offer a referance either but wowzers, I would like to have that one a lot!!!
Thanks (I think) for sharing!
