Section 708(f) in Police Regulations, Bengal , 1943
(f)If any chest, tumbril, or wagon be secured by double locks, one key should be held by the poddar and the other by the escort commander; if there be only one lock, the key should be held by the poddar, but the escort commander is responsible for not allowing the chest or wagon to be opened before arrival at its destination, save in case of a breakdown, when the treasure must be removed in his presence. In the case of remittances sent without poddars single locks should be used and the keys should be entrusted to the escort commander in a sealed cover which he should not open except when absolutely necessary in the case of a breakdown on the road.
