Your shotgun is of a pattern typically made for the European field hunter - 16ga extractor gun with sling swivels.
While I know you think your pics show a lot, in reality the most informative pics are missing - clear closeups of the proofmarks and other stampings in the metal of the bottom of the barrels, the barrel flats, and the action's watertable/flats, all nearly unviewable w/o first removing the forend and dismounting the barrels to inspect & photograph those parts.
For instance - If the barrels are marked "16-70", they are indeed chambered for 2-3/4" (70mm) fired-length shells; but if it's simply marked with a circled "16", or "16-65", then it's definitely chambered for the older/shorter 2-9/16" (65mm) fired-length shells ONLY, and should not be fired with longer ammo, even though unfired 2-3/4" shells will fit/seat in the shorter chamber.
