Historical information

It has been suggested that it is possibly part of the clockwork mechanism of the third order Fresnel lens, which was a component of the Chance Brothers lens system introduced to the lighthouse when the optics were upgraded in 1913, and subsequently removed in 1975. Further research may confirm its association with the lens and increase its heritage importance.


The well-made brass fitting has second level significance as a possible former component of the clockwork mechanism manufactured by Chance Brothers in c.1912.

Physical description
