I had an old bronze copy I did many of the nose plate from the coppergate helmet lying about and decided to set it in a chunk of pewter and set glass cabochons in its eyes. A total fantasy piece but I dont think it would be too out of place in the correct setting.
Weight is made from a cast piece which has been stuck into a piece of pewter, patinated and polished. Please note these are props and accurate weights cannot be guaranteed, feel free to contact me if you'd like to know any more.
