The guage is not always stamped on the lug along with the frame size.
When it is, it will usually be perpendicular to the frame size stamping. And a lot of times it will be stamped first and then the frame size. But, these statements are just what I have generally seen and there is always departures from the norm.
Another explanation is that the barrels could have been sleeved from 12g to 16g.
Look for sleeving lines in front of the chambers.
