Actually, this museum will be a great place to visit.
The firearm collection looks extensive from the brief shots of it in their video, but seems to be mostly automatic weapons and crew served weapons. Many tracked vehicles, etc.
The only flintlock shown in the video is the Dutch musket from Morphy's Auctions Oct 2019 auction. Seeing as how the museum has a military history theme, I doubt that there are many longrifles.
