If the bores still measure .729 and the chambers haven’t been opened past 2 1/2”, that is a victory right there in an old French gun.

Fab likely knows where that action was produced, it is a very common boxlock, usually sold in the white, that was used by everybody in France and Belgium. You don’t see many with ejectors, fewer still with single triggers, but, both are out there.

Nice gun. In the ball park on age, take it out hunting or to the club.

Best,
