  "abstract": "We have recently confirmed the planetary nebula (PN)nature of PM1-242, PM1-318 and PM1-322. Here we present high-resolution long-slit spectra of these three PNe in order to analyze their internal kinematics and to investigate their physical structure. PM1-242 is a tilted ring and not an elliptical PN as suggested by direct images. The object is probably related to ring-like PNe and shows an unusual point-symmetric brightness distribution in the ring. PM1-318 is a pole-on elliptical PN, instead of a circular one as suggested by direct images. PM1-322 is spatially unresolved and its spectrum shows large differences between the forbidden lines and H$\\alpha$ profiles, with the latter showing a double-peaked profile and relatively extended wings (FWZI $\\sim$ 325 km\\,s$^{-1}$). These properties are found in other PNe that are suspected to host a symbiotic central star.",
