Why the mystery turret photograph cannot yet be shown

Can the photograph of the possible early triple turret be shown with permission?

No permission is likely, so the photograph's source must be traced and corroborated through accessible records.

Permission to show the mystery turret photograph was requested but is unlikely to be granted. The image therefore remains a research lead whose original source and provenance must be traced independently. Other privately held naval and biographical records have faced similar restrictions from their owners or historians' estates. A credible private clue can guide archival work while remaining unavailable as published evidence.
