Very fine quality dagger produced by the Holler firm.  This was Holler's effort at producing the Water Protection Police dagger.  Eickhorn and Alcoso used a leather covered grip.  Holler chose to use leftover blue/black grips that had previously been used on Weimar era navy daggers.  This is a scarce manufacturer for this dagger type.  Grip is in outstanding condition, and ball-pommel shows outstanding detail.  Exterior brass fittings show minor wear and consistent finish.  Blade shows cleaning, with the factory etch still plainly visible on both sides.
