The army was called in to deal with the device found at Rabone Lane on Thursday afternoon.
The Explosive Ordnance Disposal team has since recovered the device for disposal.
West Midlands Police could not confirm what time period the bomb was from.
Roads were closed in the vicinity while a recovery operation took place but these have since reopened.
A spokesman for West Midlands Police said the device was an "an unexploded wartime device".
The spokesman added: "EOD [Explosive Ordnance Survey] have removed the device for disposal. Roads have now reopened."
The force encourages members of the public to call 999 if a suspicious packages is found.
Sometimes police may call in the EOD team who are experts in detonating and disposing of explosive devices.
Finding unexploded Second World War bombs in the West Midlands is not a rare occurrence, given the region was heavily bombed during the war.
