Using recent speckle measurements performed by different observers, in this paper we present revised orbital elements and dynamical masses for the binaries WDS 02396−1152 (FIN 312), 04515−3454 (FIN 320), 06253+0130 (FIN 343), 07003−2207 (FIN 334 Aa,Ab), 08291−4756 (FIN 315 Aa,Ab), 08345−3236 (FIN 335), 09173−6841 (FIN 363 AB), 09442−2746 (FIN 326), 12064−6543 (FIN 367 Aa,Ab), 12446−5717 (FIN 65 AB), 13117−2633 (FIN 305), 13320−6519 (FIN 369), 14373−4608 (FIN 318 Aa,Ab), 16057−0617 (FIN 384 Aa,Ab), 16115+0943 (FIN 354), 17221−7007 (FIN 373), 17542+1108 (FIN 381), 19035−6845 (FIN 357), 21044−1951 (FIN 328), 21158−5316 (FIN 329), 21477−3054 (FIN 330 AB) and 21579−5500 (FIN 307) discovered by W. S. Finsen using his eyepiece interferometer. A brief historical comment on Finsen's work on binaries is included. The orbital and physical properties of these stars are discussed with detail. In addition to this, quantitative results about a likely overestimation of Finsen's angular separations are provided. Moreover, the evaluation as well as the statistical significance determination of a suspected underestimation of the Hipparcos trigonometrical parallaxes at large distances is also accomplished.
