QUESTION ON PROOF STAMPING ON FRANCOTTE HAMMERGUN

3 Attachment(s)

Here is a picture of the barrel flats on a 1911 A Francote 12 GA Hammergun.
Anyone know the meaning of the D=65 divided by 20.6 m/m?

65mm= 2 1/2" or 2 9/16" chamber lenght.
20.6MM= Chamber ID, .811"

Chamber dimensions in millimeters shotguns undergoing smokeless proof. Length of chamber over diameter of chamber
