The one in the link looks like a pretty common triaxial data connector, such as the Trompeter that has been referred to earlier. As I recall the one on the 2801A (and it could be 20 years since I have seen one) is way smaller and has three lugs. It also has, IIRC, a stainless body and the outer wall is comparatively thick with a more pronounced chamfer on the outer edge.
