Vintage wooden Sonata alto/treble recorder

Description

Vintage Wooden Sonata Alto recorder. Approx. 18" long. Key of F.
Recorder plays fine, although if the recorder dries out too much the block in the head gets a little loose but it can't come out. This doesn't seem to affect the playing and when the wood absorbs more moisture, it gets tight again. A good way to keep you practicing!
It has a slightly musty smell. Has some white speckles on it. See pics for details.
