Harpeleik - it's a Norwegian-style Zither, and doesn't have chromatic notes like the German guitar-zither; instead it only has major chords.
They are 'peasant's instruments' so hence the chords config and/or the notation scribed on the body.
Having said that - a brand new or refurbished one (if you have any luck finding one) can be pricey, but also pricey to refurbish yourself if you're that way inclined.
My advice, to anyone, would just be to keep hold of it and play it - they're incredibly versatile, simple to begin with, and simply sound angelic.
