In 1911 Arthur William Sayers (born 1887) of Ilkeston was a house painter. I don’t know his occupation in 1921, but in 1939 he was certainly a house painter. However, in late 1915 he joined the Army Service Corps, though he went into the reserve and doesn’t seem to have seen service until 1918. His trade was given as “engine driver” on enlistment. Is it likely that this was a job he changed to during the war, probably to fill a shortage caused by the war?
