This is an interesting vintage wooden device! It looks like a traditional adjustable wooden book or music stand.
Here’s why:
- The angled wooden frame with steps allows you to adjust the tilt of the platform (the flat base), which would hold a book, sheet music, or documents.
- The notched mechanism on the side lets you fix the angle securely.
- Its sturdy, large wooden base would support weight and keep the stand stable.
Such stands were popular before modern metal or plastic versions became common. They’re often used by musicians, readers, or lecturers to keep materials at a comfortable viewing angle.
