WW1 Canadian CEF 1917 D.A. Brass Oiler No 1 Mk3 With Pull Through

The WW1 Canadian CEF 1917 D.A. Brass Oiler No 1 Mk3 with Pull Through is a standard-issue cleaning accessory for the Short Magazine Lee Enfield (SMLE) rifle, as used by Canadian Expeditionary Force troops during the First World War. Manufactured in 1917, this brass oiler was designed to fit into the butt trap of the SMLE, allowing soldiers to carry oil for weapon maintenance in the field. The oiler is marked “D.A. 1917,” indicating production by the Dominion Arsenal in Canada. The No 1 Mk3 designation refers to its model type. The included pull through is a cord loop used to clean the rifle’s bore in combination with a cleaning cloth and oil. Both components were essential for routine rifle maintenance under combat conditions. The robust brass construction of the oiler ensured durability and reliability, contributing to the maintenance of weapon functionality throughout active service.
