Gunn made his First-class cricket debut for Nottinghamshire in 1928 against the touring West Indians.
Gunn's century came in unusual circumstances as he was on 95 when play ended.
This time had expired with Gunn five runs short of a century, however his batting partner, Charlie Harris, convinced Warwickshire captain Bob Wyatt to resume play to allow Gunn to reach his hundred.
[3][4][5][6] After retiring from playing, Gunn took up coaching in the north of England.
[8] He died in hospital at Shelton, Shropshire in 1957 as a result of injuries sustained in a motorcycle crash.
