What I would give for a resin replica of the colt!
Wow, I don't ever recall seeing that one. What season was it used? I believe I was thinking of a different lighter, with a black tattoo'esque design last seen in Dark Side of The Moon.
As for the amulet OZ's do look great, however wheels were in motion long before seeing the finished piece. I guess the notion of having a possibly 1 off amulet might be pretty cool in itself.
I believe that the zippo is shown in the episode "Weekend at Bobby's"
Dean is flicking it open over the bones of Crowley, while talking to Crowley on the phone.
Well, I know have a 99% screen accurate salt can autographed by Jared and Jensen, a Bible autographed by Misha and a page in my journal (on the Trickster) filled out by Richard Speight Jr. Plus, I gave my awesome replica of Dean's Colt 1911 and screen accurate skull bracelet replica to Jensen as gifts at Nashcon. :-D
When I told him I wanted him to have it, his exact words were, "... seriously?" He was so surprised and happy. It was awesome. I don't have many pics of it but you can see it a bit here:
