The ring of bells at St Michael's church are noted as being one of the few rings in Birmingham still in existence that were produced before the introduction of scientific bell tuning in the 1890s (John Taylor & Co installed Birmingham's first harmonic ring at St. Barnabas' Church, Erdington in 1906). The bells' 18th–19th century tonal quality is rare as most pre-scientific bells in Birmingham have been recast by the Taylor or Whitechapel foundries.[1]
