Using a set of N-body models with different face-on bar morphology and edge-on B/PS bulges, we reproduce the kinematic features of barred galaxies seen in TIMER data. We focus on a particular case of NGC 7755, match it with our model that displays the barlens morphology and find that due to contamination by non-vertical velocity components, different components of the galaxy falling on the same line of sight and other inclination effects, the line-of-sight velocity distribution stops being a reliable indicator of the vertical density distribution features, such as the presence of the B/PS bulge. In addition, we observe the same ring of negative h4 parameter value minima independently of the presence of the barlens, thus confirming the lack of connection between these two features., The authors express gratitude for the financial support from the Russian Science Foundation (grant no. 22-22-00376).
