We present an observational study of a sample of three Point-Symmetric Planetary Nebulae (PNe): PC 19, He 2-429, and He 1-1, whose kinematics has been previously reported in the literature. The study includes an analysis of physical conditions, chemical abundances, and nature of the emission in specific regions of interest. A description of each object, taking into account morphological and kinematical data obtained from literature, is presented. We found that the abundances of He 2-429 and He 1-1 correspond to a Peimbert' Type I PNe while those of PC 19 abundances are in good agreement with a Type IV PN. Kinematic evidence derived from proper motion measurement combined with the amount of ionized mass support PC 19 classification and suggest that its progenitor star was a low-mass low-metallicity star member of the galactic halo population.
