From Rickrob2: Here’s a picture of two types of Cizek Badges. These are from Model Ones — The one with black background/gold lettering is from an earlier set S/N 1675 and 1709 when Cizek was at 149 California Street in Newton, MA and the one with gold background/brown lettering is from later set, S/N GF-1313 and GF-1315 when Cizek was at 15 Stevens Street in Andover, MA.
