It's approx 16" high; 14" wide at the base and the brackets (or whatever they are??) are approx 11" apart and protrude from the main frame approx 8".
I'm sure it's not a music sheet holder, 'cos the brackets are too deep .... but I've no idea what it could be.
To be honest, I'm not sure if it's complete ... but has anyone any ideas as to what it could be please ????
