Here is a different CD 134. The top sure looks like an American. There is what appears to be a Pennycuick bump up in the top of the threads. The skirt is at least 1/4" shorter than othe American 134s that I have here. I think one of these strange items showed up at one of the Pole Cat shows and made it into Crown Jewels. The condition is very good with the only problem being a couple of small shallow dome chips side by side. This might just be a really tough piece. $60 plus $5 for shipping.AH12
