To produce the object at all the companion that swallowed the neutron star must have been H or He burning @ most and be over 10 solar masses. Any smaller & the companion's outer layers would have been blown away by accretion onto the neutron star resulting in an LMXB system similar to the Black widows.
Expect as a result a red supergiant luminosity similar to VVcep or Mu cep rather than Betelgeuse (-7 rather than -5) May also stand more chance of producing yellow or white supergiants as a TZO.
The Metal abundances may also have been produced by the accretion of the inner layers of the SN that produced the neutron star.
