Some time ago I posted a thread about some broadheads that were labeled as Zuess Broadheads. I couldn't find any info on them and put them back in the drawer.
Recently, I came across an add in the March 1963 issue of Archery Magazine for the Scorpion broadhead from Zia Development in Pomona, CA. They sure do look like the broadheads I have. As for the Zuess reference, there was Zuess Products Company that manufactured archery equipment on Wallington, NJ.
So, the question is, was Zia Development the manufacturer, or was it the distributor and Zuess Products was the maker?
