Mike, I am weak in this area, but would be surprised that Loveless would have not signed all units, but I have been surprised a few times over the last 80 years. What I have seen in real or pictures, all were marked as I remember. Would think Stone would sign any he built also? On the other hand - possibly a "work in progress" that was sold before complete? The mag mod looks Loveless. I happened into a Loveless mag a while back (doubt most folks recognized it) and have felt like the little by that found horse stuff in the back yard, and knew that pony had to be there - but not yet.
