Earlier this year, I was told by a couple of dealers that they were not selling at all. I, of course, have them all, because I love that theater of the war.
To further Louis' point, the desert war is more interesting because from a tactical point of view, generals were free to draw up whatever plans they wanted to combat the enemy as you had open expanses with no population or natural obstacles (e.g., hedgerows), other than the sand, lack of water and the bloody flies, to get in the way.
The figures, also to Louis' point, are very well sculpted, even the earlier releases from around 2002. I would think these would be big sellers at least in the UK. I wonder if expanding the range to the West African part of the conflict would help with American buyers.
