Dunster’s property in Winchester included a shop and stall in the High Street (which were in his possession by 1417), another shop in ‘Helle’, and a tenement with a garden in Shulworth Street. By 1427 he was paying an annual rent of 40s. for another building in High Street, and a year later he had holdings in Gold Street.
Although Dunster was actively involved in the government of Winchester for 24 years from 1409, he only ever occupied minor offices, never those of bailiff or mayor. In addition to the posts listed above, he was an auditor in 1416-17, warden of the common postern in 1419-20 and auditor for the commons in 1431. One of the two citizens who formally presented Richard Bolt to the treasurer and barons of the Exchequer on 2 Feb. 1419, after Bolt had been elected mayor in place of the recently-deceased Walter Corne, he became a member of the superior body of the ‘Twenty-Four’ by October 1422.
In October 1437 it was alleged in a petition filed in Chancery on behalf of Thomas Shepyer ‘a young child [who] hath non other lyflode to be founde with duryng his tendr age’, that Dunster had refused to transfer possession to him of lands and tenements in the Soke of Winchester in accordance with the will of Shepyer’s late father. Dunster kept the will in his possession.
