Here is a Olympia Beer Ball Tap from the Olympia Brewing Company located in Tumwater, WA.  This Olympia Ball Tap Knob dates from the 1940s and is in very good condition for it’s age considering how old it is.  The face of the knob if made of porcelain enamel over copper and reads “Famous OLYMPIA” and their brewery slogan “It’s the Water”.  The body of the knob is chromed metal and stamped “Olympia” on the back so the bartender can identify the beer tapped behind the bar.
