A military post in Sambor existed from 1885-1889 and the sender could have used a 15c military rate, instead of the 25c civilian rate. The "Corr.d'Arm." octagonal gratte pmks with letters were used in Cambodia at the time, but the civilian gratte pmk used on this cover is unrecorded by J. Desrousseaux and may be the earliest known from Sambor, the first village attacked by the Cambodian dissidents
