War on Wheels and Ordnance still selling, and the third volume on the way

I had always hoped that War on Wheels and Ordnance would be of continuing interest. So it is heartening to see Amazon putting both back to full price, nearly four years after War on Wheels came out. Heartening too since the proof of third book, Dunkirk to D Day, has arrived from Pen & Sword, and I'm working through it. The story of a group of men, many of whom served in both world wars, is remarkable.
