IIRC, the most innovative part of the design was having the hammer on an eccentric so it moved up and down to contact/miss the firing pin instead of using a transfer bar or a hammer block. But that idea was used (in a little different way) in the Hopkins and Allen Safety Police back around 1913.
Hign Standard made the mistake of depending too much on one retailer, Sears. When Sears pulled out of the gun sales business (following the JFK assassination) H-S went down.
