The Healthways Deluxe single stage was first cataloged in 1960 with the "high test neoprene hose" and sold for about $52.00.  It can standard with the mouthpiece shown but for an additional $7.95 you could have it retrofitted with a Hope Page mouthpiece; a major improvement.  The original diaphragms in these regulators perished and as a result until the food grade reproductions where made available these regs had to sit on the shore.  Now all three of the Healthways double hose regulators can return to the deep.
