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 black piece, they usually come in an off white. It is in very good condition and could be utilized again if need be. Made by Sengbusch and named the Ideal Junior.
