Looking at an incoming passenger list for the HMT Empire Clyde from Singapore to Liverpool in 1953, a significant number of passengers, including the people I am interested in, have an address of c/o E.S.O. Liverpool.
I am assuming it is a military department, but have been unable to find out what it stands for.
(A number of other passengers say c/o R.A.F. Liverpool but this is more self explanatory.)
Can anyone help please?
