WW1 Brass Wheel Hub Nut - Army Transport

This is a heavy solid brass wheel nut used to secure a cart wheel. The nut is marked H. Hornshaw & Sons Builders, Dunnington. This company used to special is farm machinery until the outbreak of WW1 - so as found in France I presume this would have come from some form of British army transport. The nut measures approx 8 x 7.5 cm and is heavy weighing 533g.
