Flint pistol - Nationality?

[JamesKelly]

I generally like flint lock pistols, but don't know much about those from Europe. Picked this up in Michigan on Groundhog Day. Was told it was "German, circa 1750"
I saw that Fernando in a Jan 1 post showed a more elaborate pistol which he identified as Hungarian.
Any thoughts on this one? No markings visible, I am uneasy about removing the barrel to look for proofs.
Dimensions 425mm overall, 265mm barrel about 1/3 length fluted, balance round. About 12mm caliber, with file work at muzzle to imitate 7-groove rifling. Brass mounted, the thumb piece is reddish brass, meaning a bit lower zinc content. Ram rod replaced, stock has some repairs.

The forend cap is, I think, some distinctive style. Side plate is cut from sheet, not cast. It is hammered sheet, rather than rolled, about 0.86 – 0.91 mm thick.

What type of wood is approprate for a more correct ramrod?
In the USA we would of course use hickory, but I do not believe that hickory has been common in Europe since the last ice age. Might cow horn be authentic for the tip?
Is this muzzle “decoration/fake rifling” common to some particular area?
