This pipe had me completely fooled. It came in a collection that included a number of Ropp pipes, and this size and shape looks like a number of those pipes. As you can see, it is not a Ropp. The condition is excellent. The mark-free, amber looking stem material is acrylic. There is stellar cross grain across the back of the bowl and across the shank. The draw is open. It is a Grp. 4, but be aware that the shape of the bowl, I’d call it a Pear, means a narrow, although fairly deep, chamber.
6 1/8” long, bowl 1.6” tall. Weight: 1 oz., 30 grams.
