I'll reinforce what Vern said with a couple of photos. This is the original keychain from CSX2367, and it has the gold patina of age. I'm the collector that Vern mentioned who cast several copies of this keychain using the silicone mold process with metal tinted resin. I posted photos of those some years ago. There is also a photo of some of the Shelby items that I acquired from Vern soon after acquiring the Cobra. I'll also buy Vern's book! Dave
