Photos with the half used bottle of Fahrney's Orange (PR Orange Crush) that KCat sold to me at a very deep discount. (Thanks KCat) The color goes very well with the pen.
I am satisfied that I paid around $17 for a fully functional, almost new pen, including shipping. Someone must have replaced the sac, but it works perfectly.
I love the feel of the pen in my hand and the simple elegance that Esterbrook managed to accomplish in an economical pen. If it wasn't because of the unbalanced prices I am seing on ebay nowdays I would love to buy tens of these and their interchangeable nibs.
Some amateurish pictures below.
