Zenith "Crusader II" (right). The "Crusader II" had the Zenith name
(top) and Zenith logo (center) that are missing from the "Royal
Crusader". From the front he "Royal Crusader" looked almost identical
to the "Crusader II" except it had a shiny aluminum case and a brown
microphone grill in contrast to the "Crusader IIs" dull aluminum finish
and light-colored microphone grill. |
