RE: Movement identification: the limits of a rotor photograph · RWI-01602

Correction note for “Movement identification: the limits of a rotor photograph”: retain the wording beginning “Describe visible bridge shapes and markings separately…” in the record. If later material changes it, add the date, the changed wording and the source for that change; do not invent a completed correction here. Retain the source wording beside any paraphrase.
