Sweet Pen! Hearing of viewers being inspired by others artistry is a wonderful compliment.
The actual pen you were admiring was not one of the pens in the IAP Collection, but in my case of personal pens - that one being one of Ron Robbins (http://www.penturners.org/forum/member.php?u=13432). This is a minor detail, as you would not have seen it if not for me being there to display the IAP Collection.
