There's a man by the name of Boleslaw (Bolek) Maciaszczyck* who goes by the handle of Razpla on another muzzleloader forum. He's from Poland and makes jaw-dropping early flint and pre-flintlock firearms. He might be an "in" to the black powder crowd over there.
And boy do they reenact over there, but mostly Napoleonic era. Look up the reenactment of Borodino on YouTube. Something like 12,000 participants.
And yes, although the laws are stricter, they do shoot muzzleloaders over there.
