Hey guys.  I was going through some brass my dad gave me and I found several brown boxes(think Q3131 style) marked M193 that contained brass stamped PS and OCT 81.  They are boxer primed.  I shecked the sticky, and I doubt they are from spain, ot Italy.  Maybe the phillipines.

Korean? Poongsan Defense?  The PS looks similiar to the PSD in the pics
