1880 will likely be the date of the barrels. The "Cannonier - Paris" (barrel-maker Paris) is likely an "advertisement" of sorts for Leopold Bernard. French guns always had these with pet names for their steel, etc. Once you get detailed photos posted here, there are a couple of French contributors who can chime in and we will make progress. We have rarely commented on a Paris proofed gun. Very interesting I must say.
