Very interesting. I wonder if there are significant differences in the action procured from the three different suppliers, especially in the lower grades?
When I say that action is ubiquitous in France and Belgium, I mean it. Every gunseller in every town has a few nearly identical guns in the used rack, waiting for a new owner. 12s and 16s,usually, Demi-pistolet and superb little bird guns. Totally makes sense from the number of guns I saw that there would be more than one supplier.

The ad that points out the barrels available with or without a rib is a new one on me. Love to see a ribless French gun, not counting a Breton.

Best,
Ted
