The Romulans were Earth's first great enemies when humans first set out to explore the Galaxy. Their ship the bird-of-prey was introduced in TOS, but was redesigned by John Eaves for its appearances on ENTERPRISE. Eaves kept the basic shape, but curved the ships like a blade, The ship was also given the distinctive green color that was used for later Romulan vessels. The model is 4.3" (11 cm) across.
