Free keyboard

Can't imagine a use for a 41-note keyboard, but here is one for free that has been sitting in the closet for years now. Maybe someone can make use of it. I have absolutely no idea what instrument it was used on. Help with the postage would be appreciated. pictures at:

There are 6 pix, change the "kb1" to "kb2", etc.

Private email for takers.
