Is this a Danish percussion pistol?

I found a picture of this in a book and it was listed as "Continental" which does not say much at all. The wood and metal work, less large ring cock, might be Danish. Can anyone confirm. Butt markings are interesting, year 1830? There are no obvious proof marks, just inspection marks. 7.5 inch bbl, 14.5 inch OAL.

Looks like a Dutch Colonial M 1850 pistol. https://www.nmm.nl/zoeken-in-de-coll...m+1850+pistool

I was wrong, it's an earlier version. It's probably the Dutch heavy cavalry Model 1820/42.
