Using all available observations of the one-apparition comet 1914 II Kritzinger we show that the gravitational solution makes (O-C) residuals non-randomly distributed. We therefore apply three other models of the comet motion: (i) with a displacement of the photometric center from the center of mass of the comet along the radius vector, (ii) with a change in the velocity vector due to a single outburst of the comet, and (iii) with Marsden's standard nongravitational parameters A1, A2, A3. It turns out that models (ii) and (iii) fit the observations of comet 1914 II Kritzinger equally well and give the same mean residual and the same (O-C) residual distributions. In consequence, from the quality of the fit we are not able to distinguish which of the two models is better. It is suspected that for some comets undergoing an outburst, the model (ii) can be an alternative to, usually applied, Marsden's model (iii).
