  Some six years ago, we (Erlykin and Wolfendale, 1997) proposed the `single
source model' in which a local, recent supernova remnant (SNR) was responsible
for the `knee' in the cosmic ray (CR) energy spectrum at ~3PeV. Stimulated by
the paper by Bhadra (2002), which drew attention to a possible gamma ray
signature of this local remnant, we now study the situation for the local
source and we conclude that, in contrast to Bhadra's conclusion, the
non-observation of this remnant is understandable - at least using our SNR
model. It is due to the fact that this SNR, being local, develops in the local
hot interstellar medium (HISM) with its low density of gas and also being
nearby it will be an extended source occupying up to 40$^\circ$ of the sky and
thus indistinguishable from the background.
