The slur of A clearly refers to the top voice, hence assigning it in the editions to the bass voice is almost certainly erroneous. However, the notation of A is inaccurate, as far as the range of the slur is concerned, since it does not go beyond bar 396, contrary to the unambiguous slurring of the part of bassoon I (and of the remaining instruments), also in analogous bars 52-53. Therefore, in the main text we interpret this slur as leading to f1.
