This late war SS visor cap skull is an late war specimen, and has been attributed to the Assmann firm.  This style is without separately applied prongs. Instead, they are integral to the forming of the skull.  Produced in zinc with a silver wash or paint, this example has nice amount of this silver finish remaining.  Also present are the horizontal striations in the base metal that is common to most all of these skulls.  Unmarked, all three prongs remain.
