Belgian percussion dueling pistol, #2 of a set, cased

Elegant dueling pistol made in Belgium, rifled in  50 caliber and very accurate, Damascus barrel, case hardened in color, engraved, carved, checkered and gold inlaid, single set trigger, in reproduction case with accessories. I have owned it for decades, used to shoot this pistol in competition, hardly ever lost a match, a .490 ball and 15 thou patch over 20 grains 3F black powder  was deadly. Overall condition is Very Good as you can see from the photos. I wonder where #1 is?
