Thank you for pointing this out.
(And I think that this is the correct thread anyway.)
I checked several other Sierra Leone Battalion Medal Index Cards and 2B is a common entry.
However neither Haywood & Clarke's The History of The Royal West African Frontier Force nor Lieutenant R.P.M. Davis' History of the Sierra Leone Battalion of the Royal West African Frontier Force mention any soldiers leaving West Africa during the Great War.
Perhaps a clerical error set in in the MIC office.
