A nice renaissance alto recorder with a coupe of issues. It is by the late John Cousen (1926-2014).
I’m struggling to identify the timber, my best guess would be canarywood. Whatever it is it’s fairly heavy. The wood is in good condition, no splits or cracks, however there are a couple of chips to the foot.
It is a bit too quiet for my liking and is playing about ten cents flat of A=440, priced accordingly.
