1918 censored 'On Active Service' cover to London with a poor strike of F.P.O. '8' 25 MAR 18, the '8' being impressed only. Censored in the lower left corner by Lt. Col. Stevens, 4/1 K.A.R. (Kings African Rifles) this bears out the '8' in the datestamp as this F.P.O. was in the Mbamba Bay area in early 1918 and the Kings African Rifles were in that area as well.
