HAEF has a large archive of original documents containing the specifications of the historic cannon and other arms, to guide conservation and restoration. The example below is a page from the British Field Service Manual of 1862. It shows a schematic of the layout of a 6-pounder field piece carriage and limber, identical to the one that HAEF produced for the bronze barrel found at Barka.
