British model 1842 musket! Nepal import!

Up for sale today is a rare model 1842 musket that was sold to Nepal and kept in their arsenal until the early 00s when century arms purchased their antique arms arsenal and sold it to the collectors in America.
This is one of those import rifles. Don’t see them turn up very often. Bore is full of shellac so needs to be cleaned before it can be assessed for use. Given the exterior, I imagine light loads will be fine but given its age and condition it’s sold as is where is as a wall hanger/collectors item. Feel free to ask any questions
