That is a nice 1815 Dutch musket. And appears in good condition. Sorry I can't help with the stamps/markings. But another Forum member will likely be able to lend his expertise.
It's obvious this was a well done arsenal conversion to percussion. So common with many of these muskets. And, it looks like a rear sight was added at the time of conversion.
Many details on this musket copied the original 1763/1777 pattern French muskets of this period. In fact, the original U.S. Springfield 1795 and later variations also copied the French musket. Even the original .69 caliber bore.
If my memory serves, Belgium was a prolific in manufacturing firearms and did many musket conversions for other European countries.
Nice piece, Rick
