Could you tell me the story of Damu Anna as introduced in the Sai Satcharitra?

The story of Damu Anna is presented as an example of Sai Baba's immense love for his followers. According to Chapter 25, Damu Anna was a wealthy bronze-smith from Ahmednagar and a devout follower of Sai. He was one of two people who had the honor of providing a large new flag for the annual Ram Navami festival procession in Shirdi, a vow he upheld for many years. The text highlights that despite having two wives, he was childless but was eventually blessed with sons through Sai's grace. This story is introduced to show how Sai wards off the misfortunes of his devotees and grants their desires when they have one-pointed faith.
