It really is a brass extractor. Somewhere, perhaps at Wisner's, I saw a description of the extractors and it was described as a brass extractor. I bought one from Gun Parts, it didn't work any better than the first one. The spring is not a coil spring, it is a "L" shaped flat spring. Oldhandgunner, thanks for the offer, I'll e-mail you. I really want to start using this gun without having to carry a piece of cleaning rod around for removing fired cases. You guys are great!
