Fred - it is the shape and size of the material, after that - I have no idea. It is an odd term, probably a way to avoid the much more prosaic 'shit'. A wild guess is it was a way to speak of horse crap on television with all of its rules about language usage, especially profane words.
On the wagon park - it is just beginning, there are more to come eventually.
blue willow - yes, indeed, little touches - I 'came of age' as a miniatures gamer looking at the early photos in WI with all that added stuff and I've always wanted my games to look like the best of those photos - scatter, casualty figures, civilians, animals (wild and domestic) roaming about. Again, more to come - eventually, some sooner than later.
But first I have to focus on the 'stars of the show', the individually mounted/foot/dead sets of figures. I have a bunch to paint besides those being painted for me.
