I love these old pieces of history! This roller with vessel was used in offices to wet multitudes of stamps and envelopes. This one is the smaller with overall size at 2 ½” x 2 ¼” x 1 ¾. Check out the pictures on this green / creme piece. I have never seen one this color so I would guess this is harder to find. It is in excellent condition and could be utilized again if need be or just looks cool on your desk as a paper weight. Made by Sengbusch and named the Ideal Junior.
