This is a nice solid Spirotechnique Royal Mistral.  This is the regulator that the Cousteau team used to dive the Britannic!  The simple bullet proof design was the favorite of JYC in fact.  This particular specimen is barn fresh.  I have not cleaned it at all and it is exactly the way it arrived to the museum form Europe.  The hoses are in great shape not perished and the label is a reproduction.  The label side of the can has very nice chrome and the mech side of the can has some slight issues.  Please see the pics for condition.
