  A recent measurement of the proper motion of PSR J0908-4913 shows that it is
a fast moving object at a distance of some 3 kpc. Here we present evidence that
the pulsar is located at the edge of a previously unknown, filled-centre
supernova remnant, G270.4-1.0. The velocity vector of the pulsar points
directly away from the centre of the remnant. The putative association of the
pulsar with SNR G270.4-1.0 implies the pulsar is ~12kyr old, significantly less
than its characteristic age of 110kyr. We show that the rotation axis of the
pulsar points in the direction of the proper motion. Rotation measure and
dispersion measure variations are seen over time, likely indicating the pulsar
is passing behind a filament of the remnant.
