In 2022, we bought an Verschueren (NL) "doe orgel"

Orgelkids ‘Do-organ’ is especially designed for children to repeatedly assemble and disassemble. Children are empowered to discover how the organ is constructed and how it works by building it. The design is almost self-teaching with the help of illustrated instruction sheets. Organ builder Wim Janssen (NL) designed it, carefully considering how it would be most appealing and educational to children. They must be challenged to discover and to ask technical questions about the construction. And, of course, when the organ is built, they must be able to play music on it. Orgelkids organ has it all. That’s why we call it a ‘Do’-organ rather than a ‘demonstration’ organ.

We use this "Do-organ" in our organ-club and we use it at school classes, to promote the instrument. Children on the primary school love it to build, and to understand.
