There are known posts for Delalle - this one has the 6.5mm chamber in cm which we've been looking at - pre 1919? or 1921?

Also mentioned in previous BBS posts:

had three sliding breech shotguns. One was a Darne: one of the others was a Charlin Automatique. Proofed in St Etienne, double proof (the Darne had treble proof). I don't know what the 'automatique' was about. The other was a Delalle, also St Etienne proofed (single proof). The Delalle was dated 1914. All had mechanisms identical to the Darne.

The fact the Delalle was boring barrels in the 1900's - 1910's would seem to push the date of the gun to the 1920's. Perhaps FAB500 can tell us who was Delalle.
