A Moroccan Pistol

[Kubur]

For me, your triggerguard is maybe from Spanish origin, but original to the making of your pistol and not added later. Possibly from a Spanish riffle, it's common with Moroccan pistols. Despite the fact that the "classical" Moroccan triggerguard is very rounded, almost circular and very close to the trigger.
Netherlands were Spanish territories from 1556 to 1714. Snaphaunce, miquelet or Ripoll were common in Holland and Spain. As you know, they influenced the Moroccan weaponery as Morocco was outside the Ottoman sphere... But I' sure that all the members know that better than me.
