Here is a Wacker Beer Ball Tap Knob from the Wacker Brewing Company located in Lancaster, PA. This Wacker Beer Ball Tap Knob is from the 1930’s era and is in excellent condition for it’s age. This Wacker Knob is made of a thin lucite plastic face mounted on a black bakelite body with a threaded shank.
There are actually 2 variations of these Wacker Brewery Ball Tap Knobs. One being a generic “Wacker Beer” knob (pictured here) and the other advertising the brewery’s flagship beer known as” Little Dutch Beer”; click here to view that variation from my collection.
