This is an Eagle Prestige Demonstrator in the largest, wider size, c1939. The largest Prestige comes with a 14 karat gold Number 6 nib. The clear barrel shows the clear cylindrical ink chamber that attaches at one end to the nib section and has a short rubber sac on the other. This ink chamber unit does not touch the inside of the barrel. There are two grommeted holes in opposite sides of the barrel to allow airflow around the ink chamber to keep it from overheating, preventing leaking. The paddle-like lever that squeezes the ink sac is obscured, on the right side near the end cap. It is about 5 3/16 inches long capped.
