New Bedford police said they were called Monday to New England Demolition & Salvage by co-owner Harry James, who told them he found the device, measuring about 8-10 inches long with a propeller at one end, while unloading disarmed hand grenades and other military items from his truck, the New Bedford Standard-Times reported Tuesday.
Police and fire crews responded to the Cove Street building about 10:30 a.m. and shut down the block to traffic and pedestrians for more than 90 minutes.
A Massachusetts State Police bomb squad responded to the location and determined the device, which is believed to be from World War II, was disarmed and not a threat.
James said he obtained the disarmed military gear from the family of a man who died in January.
