Andy did do a 3-D foamtech Normandy village reminicent of the conte church back when the first polystone vehicles came out circa 1997-1998. However, it wasn't painted and came just a basic dark gray. It just didn't make an effective display for those of us without the time and talent to decorate it.
If you look on the treefrog photo gallery you will see one of my dioramas where K&C made a wonderful base with two dark gray cobblestone plazas connected by a small stone bridge (custom made at my request on the model of a Streets of Hong Kong diorama base K&C produced back then), on which I displayed many of the old 3-D wood and papier mache "back lot" buildings, along with a K&C Silk Road "Great Wall Gateway" as a medieval village wall and gate as well as a K&C Streets of Hong Kong Three Tiered Shop House building, which also seemed to fit in. This diorama is the sort of thing I would like to see K&C make today in both buildings and scenery bases. Its three dimensional, changeable, and useful in virtually any european scene you chose to depict. In fact, if Andy produced back lot buildings of European townhouses without the WWII era features (like the miniature Nazi propaganda posters), they would work as well with Napoleonic Era figures as they do with WWII figures.
In addition to cobblestone town bases, K&C could make square countryside bases, with hedgerows, fields, streams, trenches, fences, footbridges and country roads. Four or five different 18 or 24 inch square bases could be alternated to make huge dioramas that would work with any european battle from Napoleon's time to the present. Three dimensional farm houses, towers or other european country style buildings could be placed where ever the collector building the diorama chooses.
Andy could even do winter versions by merely spraying a coat of white fake snow over the bases and gluing some fake snow and ice to the various houses, making the dioramas work for the battle of the bulge or the eastern front. I think these bases and buildings would be affordable, portable and attractive to the two biggest groups of K&C collectors: WWII and Napoleonic Era. Perhaps I will discuss the idea with Andy at the Symposium.
