The rarest of the rare, US DIVERS ROYAL MISTRAL.  This is a fine example in great condition with original hoses and mouthpiece.  The Royal Mistral was US DIVERS failed attempt to make a balanced single stage.  The chrome was shiny as opposed to the flat satin of the original Mistral.  The red label really made this regulator pop.  This model was only made for approximately two years and is very rare today as many were thrown away.
