The later versions of this model were built using a single ring on the cap, always with the arrow clip and the [[jewel]] and metal rings decorations at barrel bottom and cap top. This version has been found with copies of the clip also shaped in the early versions of the pen, whose origins are unknown. | The later versions of this model were built using a single ring on the cap, always with the arrow clip and the [[jewel]] and metal rings decorations at barrel bottom and cap top.
