Arthur Court cast aluminum salmon platter

This platter is 12" in diameter and about 1.5" high. A thrift shop find and easy to identify. It is no longer being made. Not sure where cast aluminum in Court's catalog of this period (1993) was made and by which artists or studios. It is quite well done. I have only a few pieces of cast aluminum and only pick up such things that really strike my fancy like this tray did. No idea how to classify this. I'm sure that CW will help me out.
