Jim Brown was a guest player for Exeter City during the 1944-45 season, Brown had played for Motherwell. He made his debut for the Grecians in a 5-1 home win against Plymouth Argyle in March 1945. He was to also appear on a further 7 occasions as a guest for the Grecians during 1945-46.

This is possibly James Brown who played for Chesterfield & Bradford City? He had signed from Motherwell, where he'd been since 1943, in May 1948. When he arrived at Chesterfield he was put on a rowing machine in motorbike leathers to get his weight down and increase his fitness.  He was said to be homesick, as a result Chesterfield let him ho, only for him to sign for Bradford City a couple of weeks later. He played for Queen of the South & Carlisle after leaving Bradford City.
