Comparison of the Zenith "Royal Crusader" (left) and the Zenith
"Crusader II" (right). The "Crusader II" reversed the Zenith name and
microphone grill colors. From the front he "Royal Crusader" looked almost identical
to the "Crusader II" if you didn't notice the colors were
reversed. Also, the "Royal Crusader" had a shiny aluminum case in contrast to the "Crusader II's" dull aluminum finish. |

showing the green filter installed in the nubbin and the red washer on
the outside of the nubbin. The purpose of the washer was to make a
tight seal between the ear mold and the receiver to help prevent sound
leaking out and causing feedback.
