The arms of the 
hairpin in A are of different length; however, in this case it is almost certain that it is the top arm that has to be taken into account – an extension of the bottom arm to the left would make the dots over the L.H. minim blurry. In FC the mark is shorter, and in the editions the range of the mark was adjusted to the group of quavers, which is actually of no significance in this case.
The absence of both marks in CGS is most probably an oversight.
As has no hairpins, and the long accent in the previous bar is the only mark of this type.
