With reference to the swastika and the little 'ends' this is a representation of the Sonnenrad, or Sunwheel, style of the swastika. It is an ancient Norse representaion of the sun. This Sonnenrad was found quite often on various early Nazi pieces of equipment, the early SA enlisted mans belt buckle, the early Luftwaffe Officers dress dagger and other items.
