context_page_description: The Ordnance BL 60-pounder was a British 5 inch heavy field gun designed in 1903–05 to provide a new capability that had been partially met by the interim QF 4.7 inch Gun. It was designed for both horse draft and mechanical traction and served throughout the First World War in the main theatres. It remained in service with British and Commonwealth forces in the inter-war period and in frontline service with British and South African batteries until 1942 being superseded by the BL 4.5 inch Medium Gun.
context_section_description: The Mk II gun introduced from 1918 had a longer barrel, new box trail carriage giving increased elevation to 35 degrees and cut-off gear to automatically reduce the recoil length from 54 to 24 inches with increasing elevation, hydro-pneumatic recoil system below the barrel, single-motion Asbury breech. It arrived too late to see service in the First World War and was effectively a new weapon. The gun was one of two types that could be carried by the Gun Carrier Mark I.
