Good Pair of WW1 Era Cavalry Officers Leather Boots

A super pair of WW1 era officers riding boots, they come complete with their top fastening strap which attaches to the leg, they have their laces but these appear broken and shortened. The pair are in very good solid condition, there are signs of age and use with some scuffs to the leather but a good feed and polish should get rid of some of the marks, I would estimate them to be a size 8 and a slim fit.
