The Viol. indication, added in GE1, may be authentic. Chopin could have had two reasons to specify the instrumentation: the reduction does not include here an important motif of the flute and oboe; moreover, in GE1 the dots and the slur written in A were overlooked. The possibility that the articulation markings were deliberately replaced with this indication seems to be much less likely.
