Who was Damu Anna and what was his relationship with Sai Baba as introduced in the Satcharitra?

According to the narrative in Chapter 25, Damu Anna was a well-to-do person from Ahmednagar, specifically a wealthy Kasar or bronze-smith. He is described as a great devotee who was deeply devoted to Sai Baba's feet. The text uses his story as an example of Sai's profound love for His followers, stating that once one-pointed faith is established, Sai wards off all misfortunes. Damu Anna's devotion was demonstrated through his long-standing vow to provide one of the two large flags for the annual Ram Navami festival procession in Shirdi, an act he performed with uninterrupted love and devotion for many years.
