Bach - Prelude and fugue no.9 in E major BWV 854

[mammy]

I still desperately need the fingering for the fugue. My son's teacher is for a while abroad and he is studying now only with somebody who's struggling for two weeks with the fingering. I will be grateful forever. the time's passing and he should have started to work it until now. He has got the fingering only for the prelude and the first three rows or so. Thank you!
