US Divers Vintage Tank & Valve. FROM THE EARLY DAYS OF SCUBA. This tank and has been stored in my closet & not been used in years. The tank without valve is approximately 25 inches tall and 7 inches in diameter. The Aqua-Lung sticker on the tank is the original. There are a few other pieces in my store. SCUBA equipment should be considered “life support equipment”. If you have any questions, just ask.
