Musical instruments of all types (Farden SY8)

We are sponsoring a primary school for blind children in Uganda which has no government funding. We took them some musical instruments when we visited a few years ago, and they have now asked us for more, as they have an excellent music teacher. Has anyone got any old instruments they could spare? Percussion or woodwind would be most suitable. We will collect from anywhere in due course. The children are delightful, and any contributions will be really appreciated!
