Reports mentioned in the discussion identify definite 12-inch triple-turret work and possible 14-inch work by British firms. An Armstrong design associated with Italian requirements suggests that British engineers were working on triple mounts before the Royal Navy adopted them. A surviving photograph and later Armstrong information increase confidence that at least one example was constructed in the United Kingdom, although its date and exact form remain uncertain. Vickers involvement is inferred from industrial rivalry rather than directly established in this passage. The evidence supports an archival search for British-built models or turrets, while a specific Royal Navy ship design remains unproven.

Armstrong, Vickers, and British triple-turret evidence
Possible Armstrong and Vickers triple-turret designs lead to an archival question about what British firms actually built or proposed in the prewar period.
