An 'A' Clamp, environmentally sealed diving regulator with 3 low pressure ports and  one high pressure port, in working condition.

The low pressure hose is for illustration purposes only as it is out of date. I  can supply it  if its required.

In a very good condition with only a few marks on the surface.

Used until 5 years ago .  

Note this regulator will need a professional service if it is to be used in the water.
