This is an early 6 hole French Flageolet. These instruments were popular from the 17th to 19th-Century. I’m not sure of the date of this one - could be late 18th century. It looks as though it was made by someone who was a real recorder maker which would place it fairly early. It does have a makers mark but it is quite worn and I can’t identify any of it. Pitch is around A=425 with the lowest note sounding A.
