As the title states this plaque is of a, so far unknown, sergeant of the Hungarian army. It has a diameter of almost 33cm and weighs 5kg! Any help with establishing who the sergeant is would be most welcome!!!
The artist who designed it is Turáni Kovács Imre who was born in 1910 and died in 1975. More details about his career you can find here.
The foundry that produced the plaque is also given on the bronze!
The front seems to have some old damage that was there when the plaque was repatinated or gilded at the outside again. This also seems to have been done a long time ago. My guess this plaque was placed at a house but where and why is unknown.
