Georgian Dragoons or Hussars Silvered Officers Helmet Plate

A really magnificent item it carries It is a large item 5' tall and 5' wide. It is a Maltese 8 pointed cross carrying The Georgian Crown and Coat of Arms to the centre with the rose of England and Thistle of Scotland above the Dieu Et Mon Droit motto. It is silver plate on Copper. Some old solder repairs to the rear which don't detract from the front. 8 double wire fixtures to rear. Not sure of the actual unit but I have seen similar items dating from this era.
