That's a very nice stick indeed!

If its to be used on a double rifle, the metalwork would need to be very well adorned to 'keep up'. It always looks strange to me to have a plain boxlock fitted-up with wood of that quality. These days most newly-made DG-calibre DRs are workhorses which will be carried a lot in the hunting-car and through the thorn, occasionally soaked in sweat, rain, and blood, etc. Of course they should look good, but the days of the Maharajah posers are over!

The blank would be more at home on a fully-engraved British-style 12-bore game-gun than any rifle IMHO. Then it can be displayed to best effect, standing on the line in a gentlemanly fashion waiting for the beaters!
