This is a sabre made for Lt. L.C. Moon who served in the Royal Field Artillery during the First World War. It was most probably made using a recycled cavalry sabre, as attested by some of the remaining stamps on the ricasso such as WD and YC. This results in a massive artillery sabre, perhaps to fit the size of its owner.
The blade is pitted in some areas, and the guard is patinated. The whole sword is perfectly solid. The scabbard does have some fraying, but is generally solid.
