We present a detailed analysis of the new planetary nebula (PN) IPHASXJ193718.6+202102 using deep imaging and intermediate- and high resolutionspectroscopy that are interpreted through morpho-kinematic and photoionisationmodelling. The physical structure of the nebula consists of a fragmented torusand an extremely faint orthogonal bipolar outflow, contrary to the pinchedwaist PN morphology suggested by its optical image. Our kinematic analysisindicates that the torus is expanding at 25$\pm$5 km s$^{-1}$ and is graduallybreaking up. At an estimated distance of 7.1$_{-0.3}^{+0.8}$ kpc, thecorresponding kinematic age of $\sim$26000 years is consistent with a faint anddisintegrating PN. The intermediate-resolution spectra reveal an excited PNwith chemical abundances typical of Type II PNe. Based on the latter we alsoestimate an initial mass for the progenitor in the range 2--3 M$_{\odot}$ and acentral star (CSPN) mass $M_\mathrm{CSPN}\sim$0.61 M$_{\odot}$. The SpitzerMIPS 24 $\mu$m emission that closely follows the fragmented torus could beattributed to the emission of [O IV] at 25.9 $\mu$m rather than to dustemission. All the results coherently point towards an evolved moderatelymassive bipolar Type II PN on the brink of dissolving into the interstellarmedium.
