Here is an original Selmer "Air Flow" C* tenor mouthpiece. This mouthpiece measures .072" on my gauge.
This piece is from the 1950's and was the precursor to the now legendary "Soloist" design. I find this to be a huge leap in design from the cavernous chambers of previous models that were stamped "air flow". This generation would have been included with Super Action saxophones or very early Mark VI instruments. What is remarkable is the tight, round squeeze throat that centers the air very quickly and easily.
This is the same model that was used by Sonny Rollins on the album, The Bridge. If you examine the photos closely you will see the slightly 'stubbier' shape of the scroll shank.
Air Flows from this period make excellent candidates for opening up to more contemporary sizes as they become quite powerful and retain plenty of warmth.
