Here is a blue NN No 9 in very good condition. Two small open bubbles on the base, a little scuffing around the wire guide and roughness around the skirt edge. Huge bubble in the skirt to the right of the embossing, with two smaller ones above it in the lower wire guide, and another small one above and to the left of those in the bottom of the dome. Solid dome glass. Asking $30 + shipping.
