From the Bulldog 120 a four-seat sports and touring aircraft was developed, intended for the civil market, known as the Bullfinch. The prototype (G-BDOG c/n BH200-381) was flown for the first time by chief test pilot John Blair on August 20, 1976. The military version, the Bulldog Series 200, was intended to complement the fixed-gear Bulldog 120. Within a month after the maiden flight the first sale of a single aircraft was announced, but the company was not successful in finding further customers, either civil or military. In 1977 Scottish Aviation was taken up in British Aerospace and the Bullfinch was subsequently cancelled.
