 Richard William Mercer, now a private citizen after being demobilized from Military District 10 in Winnipeg, undertook the duties of the Theodore Post Master from September 1919 until his retirement forty-seven year later in 1965 at the age of 68 years of age. His wife Salbjörd Mercer often worked as the Assistant Postmaster, especially after the children were all grown.
 There is a panoramic photograph of most of the Saskatchewan Postmasters in front of the Bessborough Hotel in Saskatoon, Saskatchewan. The hotel is still under construction in circa 1926 (?) with a portion of the "castle" roof still being shingled. The photograph is in the Mercer family collection.
 The new Theodore Post Office building is purchased in 1919 from the town doctor, Dr. Eakins, and just before he left to return back East. The role of Post Master was assumed from the parents of Richard Mercer's late best friend Pte. Tom Tracy. The "circle" from the Great War is now complete.
