You might want to check to see if a new owner is building Francotte shotguns again. I have a 16 ga O/U 9/40E S-33 that is as nice a gun out there. I'm sure you could have a special order built IF they are again available. The S-33 was the highest grade boxlock Francotte made. They also made a sidelock O/U but I have never seen one. There is a 12 ga S-32 O/U for sale listed on a dealers website. You might find it on some type search mode. It will give you an idea of how they are made and how they look.
