1,200 acres, centred on Chillesford Lodge, the model farm established by Sir Richard Wallace in 1875/6, situated half a mile west of Sudbourne Hall. Alastair Watson continued for a while to maintain the famous and long-established "Sudbourne" prefixed herd of Red Poll cattle and the "Sudbourne" stud of Suffolk Punch heavy horses, which won several prizes. In the 1930s part of the former Sudbourne estate was acquired by the Forestry Commission, including Chillesford Wood (from the Watsons) and Sudbourne Wood, and are today part of the Commission's 1,170 hectare Tunstall Forest, together with Gedgrave Broom, held on lease. The Watsons' estate was further reduced by two more sales of land, in 1927 and 1930. In 1936 Alastair Watson built the Chillesford Polo Ground, a private club open to family and friends where teams played by invitation only. It represented "country polo at its best" and used an advanced system of irrigation sprinklers, then unique in England, imported by Watson from the USA where he had seen them in use at the Santa Barbara Polo Club in California. Spectators were encouraged and were admitted free of charge, with printed programmes with colour covers provided, a further innovation for a small polo club at the time. The club closed during World War II but re-opened in 1948. Alastair Watson is said to have been trampled to death by ponies during a polo match, after which the polo ground was ploughed up. The Chillesford Lodge estate remains the property of George Watson, ex-Royal Navy who served on the Royal Yacht Britannia, one of the grandsons of Alastair Watson, who has converted the model farm buildings (some displaying Wallace's heraldic crest sculpted in stone) into multiple housing units. Lyon Following the death of Lord Manton in 1922, Sudbourne Hall together with 196 acres of land and seventy-six acres of woodland was purchased by (Jeremiah) Malcolm Lyon, of Jewish origin, who having been divorced by his first wife Maria Eliza Soper in 1913, had lived with his second wife during World War I and until 1920 at Heywood House near Westbury in Wiltshire which they operated as an "auxiliary hospital for wounded soldiers where they could rest, recover and recuperate from injuries and trauma". His sons included Malcolm Douglas Lyon, Chief Justice of the Seychelles from 1948 to 1957 and Beverley Hamilton Lyon, a co-founder of Rediffusion, both of whom were notable County Cricketers. By
