I picked up the CD 145 on the right this week and I'm not for sure what kind it is. The one on the left I have as a 145 No-Embossing Grand Canyon. The one on the right kind of resembles it but the threads are way off. The one on the left has fine threads and a "tit" on the inside of the pinhole. I'm wondering if it a Pennycuick style instead of Grand Canyon. Anyone have any idea's? Anyone have a picture of the 3 different No Embossing 145's? THANKS!!
