Me and my dive buddy where doing some work at Aquarena Springs in Texas and found an old mask buried in the mud. The glass was gone but the rubber was in good shape. Oval shaped with no way to pinch your nose and the rubber has to be 3/16th of an inch thick with no feathering around the edges. Divers have been maintaining this part of the lake for the last 60 years and I was wondering just how old this mask could be?
