Well, I'm VERY lucky, as I bought one here recently made custom by an unknown smith, but it has proven to be well made and uses US made Cochran locks, who used to sell them to Dixie Gun Works. The only other option than that UGLY Pedersoli double is one from India. And that Pedersoli is sooooooooo butt ugly to me .... (HORRIBLE checkering design, ick, iCk, IcK, ICK!) that I think I'd take my chances with the ones from India.
Slim it down, tune the locks and then refinish both the metal and wood and it would be much prettier than the Pedersoli, at least to my eyes.
But I would bet you possibly could talk a great metal smith and gun artisan like Brian Anderson, of Bristol, VT to make you one. PM me if you need his contact info.
