This peal of six bells were cast by Thomas Mears of London in 1833. They were not well in tune and had distinctly old style harmonics.
In 2018, we retuned the bells to true-harmonic standard, by removing metal from their inside surfaces and also by re-profiling the outside of their soundbows. The transformation in sound is quite remarkable.
All six bells were rehung with all new fittings in the existing bellframe, which has been restored and strengthened.
