(5) Royal Arms of Edward VI - the only arms of this reign and so, but for Rushbrooke in Suffolk (TQ 86 SE 78) the earliest of all to survive in England. Depicts a few early Renaissance details typical of the period (1547-53). Every window is harshly and pendantically renewed. Tenlon made 'alterations' in 1854. Another restoration in 1882. (6) Additional bibliography - not consulted. (7-10)

In 2013 English Heritage undertook a dendochronological analysis of the oak boards of the Royal Coat of Arms for Edward VI from the Church in an attempt to verify its date precisely. It was concluded the wood used in the boards was used after AD 1541 but before c. AD1573. This supports its attribution to the reign of Edward VI whereas most surviving coats of arms date from James I or later. (11)
