This International Divers two stage Navy Type was obtained by the museum in Ontario Canada. It came complete with the one piece hose assembly and a repair tag from August 1966. It listed a new hose assembly for $12.95, HP seat for $3.15, Horseshoe for $5.50, hinge pin 50 cents, and duck bill for $2.75 for a grand total of $29.85 after the $5.00 in labor was tacked on. Oh how things have changed. This regulator had no one way valves in the mouthpiece so one had to roll to clear it.
