Later in 1958, Kässbohrer built the forty-one Silver Eagles. This factory run had the same general external look but with a lesser interior specification. Gone were the galley and tables, which were replaced with forward-facing seats. These were called Silver Eagles as the golden-colored aluminum sides were replaced with silver-colored paneling. The Silver Eagle became the new standard coach of Continental Trailways.
As with the 1956 Golden Eagle prototype, Continental wanted to build up some time and mileage on these new coaches before deciding on what changes to make in the next batch. Continental wanted a new front end design and a standard American powertrain and presented these ideas to Kässbohrer, who agreed to them. Design work started and production was scheduled for the middle of 1960.
