This is a good example of the popular 1908 cavalry trooper sword. The sword itself was made by Enfield in 1915. There are no unit markings left on the sword, but thr scabbard is marked to the 6th Dragoon Guards or Carabiniers.
The Regiment was one of the oldest in Britain, and served in many of the largest battles of WW1 including Marnes, both battles of Ypres and the Somme among many others.
The sword’s guard and scabbard are pitted but in good general state. The scabbard has a few bends. The blade is in pristine shape and is quite straight and service sharpened. There is a slight movement in the pommel that could be corrected by tightening the screw.
