Thanks, Ted. I didn't realize that. I have a Darne brochure from a gun shop in Rouen, which I must have picked up in 1977 when I was there with a group of American college students. In addition to the traditional Darne sxs, the brochure shows 3 different OU models which, from the brochure, Darne claims to be making. Other than that very typical small round knob French grip, they look to be pretty much standard top break OU's. And that's how the brochure describes them. I don't recall actually seeing any of those Darne OU's in the shop in question. But I was probably focused on the sxs, and may have missed them.
