| Eagle Rodded Flat Back |
Clicking on a picture will bring up a larger view in a new window.
| The rodded flat back is the most commonly found of the early Eagle signals. The flat back was produced following the Eaglelux. The casting was heavier and the flat back was more damage resistant than the earlier Eagleluxes. |

The reflectors are glass mirror type. Each reflector frame hangs from a thin tension rod. Unlike the Eaglelux each reflector also has a tension wire on its swing side that rests in a notch on the signal frame. This design also allows the reflector to be suspended slightly forward. When the signal door closes, the lens gasket pushes slightly against the reflector, the pressure is taken up by slight flexion in the rods and a dust tight seal is maintained.

This flat back has the classic door hinges where the door hinge arms straddle the frame hinge arms and are held in place by roll pins.
The latch is a wing nut on an L-bolt that is held in place by a crimp ring. |

| The rodded flat back lenses still had the earlier "Stop" and "Go" semaphore flags logo. |
