The CD 147 on the right has been in my collection for some time. The one on the left is the one my friend Steve sent me up from Cape Coral Fl. He thought the color was different when we traded pics for a trade we were going to make for one of those CD 145 Mini B's that I found from a previous hunt. I was a tad disappointed when I discovered the color was pretty much the same. However to my elation I discovered that they were both made from different molds. I noticed that the spiral wire grooves were opposite when the same embossing side were placed in my window. So thank you Steve. If we at ICON didn't know before that there was more then one die for these, we all do now!
