The unseen companion of BD +27°4120, CC 1299, was discovered in 1964 from plates taken with the Sproul refractor from 19399-63. The observations extending to 1979 are satisfied by a period of 85 years. With an adopted mass range for CC 1299, 0.44-0.55Msun, the most likely mass for the unseen companion ranges between 9.23 and 0.29 Msun, with Mr ∼ 13. This interpretation leads to a somewhat underluminous Ni dwarf companion. The semi-major axis of the photocentric orbit, α = 0"436 ± 0".004 (p.e.) and the Sproul absolute parallax, π = 0".081 ± 0".002 (p.e.).
