The nongravitational motion of three short-period comets - discovered in the twenties and running on similar heliocentric orbits - has been investigated. We used the Sekanina's forced precession model of the rotating cometary nucleus to include the nongravitational terms into equations of the comet's motion. Values of six precessional parameters: A, η, I, φ, f_p and s have been determined along with corrections to orbital elements from astrometric observations of the comets. We were able to link successfully all the observations of each comet over interval of time spanning about seventy years. According to our solutions, the nucleus of comet Reinmuth 1 is oblate whereas those of comets Forbes and Wolf-Harrington are prolate along the spin-axis.
