Abstract
More than 160 photoelectric radial-velocity measurements allow the see mingly discordant set of radial velocities measured for HD 176695 at t he David Dunlap Observatory around 1950 to be explained as a periastro n passage in a highly eccentric orbit with a period of 21 years - the longest: period determined so far in the present series of papers. The only plausible explanation for the very large mass function of 0.5 M( circle dot) is that the secondary object is itself binary.
