I'd say it's certainly a Klein Kirsten - that's a lady's road/touring model. Compare the light blue frame bottom left in this catalogue page from 1989:

I know Klein had some odd methods of frame sizing, but I guess 47cm centre-to-top must make yours the 47cm model. The catalogue says new for '89, so at least you know it can't be older than that.
Here's a better picture from 1990:

Both those pictures are linked from the blog page I posted above.
Calmes dans le demi-jour
Que les branches hautes font,
Pénétrons bien notre amour
De ce silence profond.
