Vanvlak, please help me with some explanations: why do I see a lot of different scaled miniatures together on that picture? Maybe I'm too dumb, but I don't get the meaning of your entry. Especially the large elephant behind the small tanks irritates me ...
Hope you don't take it as an offence, but I'd like to understand before I give my vote.
No offence.
I think you can put it down to scale creep.
All the models (except for the mish-mash tractor and the suit) should be 15mm scale. The elephant comes from Old Glory (I think...); the tankettes (hence the small size) were donated by a friend and come from an undetermined range. The tractor is a lash up, with only the handrail (barely seen in the detail shot) and the view port (again barely seen at front, below the engine) giving any clue to scale. The suit belongs to 10mm scale (as a large robot thingy) but fits a 15mm model beautifully as a body suit. The 'alien vehicle' was another donation, and looks larger in the pic but is not. I think the paint area (which appears in the background to right) is a bit, umm, disproportionate....
