Can you provide a detailed account of the story of Damu Anna from the Shri Sai Satcharitra?

The story of Damu Anna is presented as a prime example of Sai Baba's love for His devotees. According to Chapter 25, Damu Anna was a wealthy Kasar (bronze-smith) from Ahmednagar who was deeply devoted to Sai. Although he had two wives, he was without children, a significant source of suffering. However, by receiving Sai's blessings, he was eventually blessed with sons. His devotion is also highlighted by his long-standing vow to provide one of the two large flags for the annual Ram Navami festival procession in Shirdi, a commitment he fulfilled for many years with uninterrupted love. This story is shared to show how Sai wards off the misfortunes of His devotees once they establish one-pointed faith.
