All original 1958 AquaMaster regulator and 1960 US Divers constant reserve J valve.
Contact me for photos.
This regulator has been identified as a late 1958 DA Aquamaster. That is indicated by the presence of box clips on the can, instead of a ring and screw attachment, and the lack of a serial number. The presence of a hookah port indicates it was manufactured late in the year. (Source: [link removed by eBay] /wp-content/uploads/2015/07/da.pdf).
To my knowledge, he regulator has never been serviced. The metal box clips (phased out in October 1958) securing the can show no tool marks that would indicate it has ever been opened.
The regulator works, however there is an internal leak and breaths hard. Not surprising for a 67 year old non-serviced regulator.
There is no corrosion.
The hoses are in fair condition with some cracking. It looks like a repair was made to the exhaust hose, which has a split near the can.
The "Kleer E-Z" mouthpiece is in good condition. The non-return valves are intact, but worn.
One of the Tinnerman hose clamps is broken.
The label still has vestiges of blue paint.
The Model J-60 (501J) tank valve is dated 9/60.
It has a dented nipple, so unless it is re-machined, it can only be used for display.
The dent is shown in the pictures.
