On the 1925 electoral roll - Edward Howard Balden and his wife Edith are listed at 137/139 - which is in Kelly's as the Estate Office and, I assume, a house for them. On 1911 census he was described as "estate manager".
In 1935 Guy and Ellen Heaton and Olive Bissett were listed.
In 1939 the address was not listed - it jumped from Plough and Harrow to 141.
