I have a set of bookends I picked up a while back......they are made of solid oak and have metal pins. Whoever made these did a fine job, they have a screwed joints and have green felt on the bottoms. Rock solid. Also appear to have a coat of polyurethane on them. The CD 104 insulator is not included. I'm asking $15 + $5 to help out with the shipping. E-mail with any questions and thanks for looking.
