I'm not sure what exactly led to this problem, but the corodinates of this object are grossly in error. I spent nearly an hour trying to platesolve it, and discovered that the actual nebula is located nearly half a degree to the south, at J2000 coordinates 03 27 20, +45 24 30.
It fits with the image made of the object in this paper (labeled as HW 4) http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?1996ApJS..107..255T&data_type=PDF_HIGH&whole_paper=YES&type=PRINTER&filetype=.pdf
all the way down to a similar double-bow shock on the northwestern end of the nebula.
The progenitor white dwarf is probably Gaia 241918950690107264 at 03 27 15.41 +45 24 20.5.
Edit:
PN G149-09.0 doesn't seem to have existed in the first place. It was a mistaken notation in the 1996 paper while everything else was given properly.
