A possible 1907 constructors-course triple-turret lead

Family notes may indicate that a triple-turret possibility was taught on a constructors course in 1907. If corroborated, that would make the concept less radical inside British design circles than later practice alone suggests. The notes survive as small fragments whose meaning and provenance are not yet established. The passage illustrates how an intriguing lead can guide further archival work without becoming a confirmed fact.
