E.A.R. & H. = East African Railways & Harbours. E.A.R. No. 110 → serial number of the locomotive or boiler. EXAM: 5.9.68 → Last internal inspection recorded in Nairobi, September 5, 1968. The number 3888 appears likely consistent with the era in which North British built locomotives for the African colonies, but it does not directly correspond to well-mapped classes such as 29 or 30, whose Works Number series were higher and dated to the 1950s.
