Yes, a CD 731 threadless. But it is mint and it does have an unusual and large milky "N" as seen in the photo. Good addition to the 731 display. Got it from a nice older Canadian gentleman set up at the show. He told me that it had been in his collection for 30 years. I had been looking at other items on his table all weekend and he had just pulled this one out of the box on Sunday as I walked by. Now that's something that rarely happens to me!
