Several designs of Eagle are distinguishable (most obviously by the detailing of the leg pods). The first 44 inch Eagle and first 22 inch Eagle appear prominently throughout both series. The second 44" Eagle first appeared in The Last Sunset). The third 44" Eagle first appeared in The Exiles. The second 22" Eagle only appeared briefly in The Bringers Of Wonder part 1.
A larger scale partial model of the Eagle was made, consisting of some superstructure. It is seen with model astronauts in The Bringers Of Wonder part 2 and the top-mounted laser in The A B Chrysalis, Devil's Planet and The Seance Spectre.
Photographic cut-out Eagles were often spotted, in the various hangar scenes plus in Missing Link, The Full Circle, Guardian Of Piri and War Games (being blown up).
A special large leg pod in seen in The Metamorph (detailing bears little resemblance to any of the actual models)
