Yes, I acquired one chambered in 9,3x74R 23 years ago. It's called the CCS25 (Carabine à Canons Superposés = o/u rifle) Very well handmade rifle based on a 20 ga B25 receiver (differences are that for the CCS, the bottom wall is not hollowed out, sides are thicker overall and heat treatment is adapted to rifle pressures). I've fitted a Swarovski 1,25-4x24 scope in Sühler claw mounts and use it for drive hunting (running game). Mine is very accurate and shoots both bbls. in the same hole at 50 meters. FN-Browning's custom shop still makes them on order (engraved, luxury grades only and priced accordingly) along a newer line of less expensive doubles (CCS525) where rifled bbls. are retrofitted to finished B525 20 ga shotguns and often come with both smooth and rifles bbls. Of course, these can't be compared to the originals, but then they sell at half the price...).
