It certainly wasn't Noel Boyd, Your assumption that just because it was a C model and had a G on it! it was Noel is far wide of the mark and a bit insulting to a guy that spent a lifetime on venison and never bent anything. The same letters were issued to operators,remeber there were more than 26 venison operators back then,the background colour of the circle is also a determining factor of the operator.
My guess is it is ZK-HPS in the central north island.
