Research Note: Factory records suggest this run is composed of "Grade 182" movements. However, this is the only run designated as Grade 182, and surviving examples are consistent with the standard Grade 183 classification. For this reason, it has been concluded that the run is represented as Grade 182 due to a factory records error or transcription error. The database has been updated accordingly to align with a Grade 183 classification.
