The early No.1s got Douglas Premium barrels and the M77s got Douglas standard barrels.


I think all Douglas barrels are called Premium.Airgauged is their "better barrel".


Huntz, according to their web-site, barrel grade(standard and Premium) and air-gauged are two different things. I believe they have always done this (circa 1968 in the case of Ruger barrels) but I can't reference that.
