Wanted: 1892 Darne Rotating Breechlock Shotgun

I am a collector of unique actions and old shotguns. 

I am looking for a Darne rotating breechlock shotgun, 

Does not have to be an 1892, would also consider an 1891 or  ????

I am also interested in other old shotguns if they have unique actions.

Let me know what you have. 

Scammers, no need to bother trying with me. 

Thanks for your consideration.
