|1:285 scale Hummel 150mm SPG from GHQ|
This is an old model from GHQ. I first saw it featured in an advertisement in Military Modelling or the Airfix Magazine — the tagline was "Fight the Desert War in a small way", and they called attention to the shovel on the left hull rear as an example of their attention to detail.

It would appear that it has been re-mastered since then — no shovel any more, but even more detail everywhere else.
