I have 2 of the 2nd from left, 6 of the 3rd from left, and 3 of the far right. All I know is that they are engraved "Sheaffer", but nothing else. The 3rd from left were sold as "School Pens". If I Google "Sheaffer School Pens", the 3 on the left will appear. The one on the right appears labeled as a Viewpoint.
If you know what they are, please let me know.
