Tory Island retained hyper-radial optic component

Derived optic component from the original Tory Island Chance Brothers hyper-radial optic. Source synthesis records that the original tri-form optic was divided/re-engineered, with one biform optic continuing at Tory Island Lighthouse.

Evidence note

Official Irish Lights Tory Island page supports the 1923 biform optic at Tory; hyper-radial split lineage is corroborated by public hyper-radial reference material.
