I was able to add five nice threadless to my collection this past November at the Springfield Show. Now that I' ve finally figured out how to take okay photos of them, I want to share them with you. Note especially the comparative shots of the 731 and 731.2 as in this first photo. I've noticed some confusion in the hobby with this distinction so I hope this helps. Later I'll post a shot of the trio---731, 731.2, and 728. Both of these are in great condition.
