Very intersting discussion indeed. I have always thought that the 6-pounder was an excellent (although late) replacement for the 2-pounder in British service. It was very valuable in defence especially in the desert but even in Europe 1944, but less suited for the 'Blitz-krieg' like tactics of the allies in France. Maybe thats why the Americans preferred the much more mobile and hard-hitting Tank Destroyers like M-10 ? I can recommed the book: 'Breaking the panzers (The bloody battle for Rauary normandy 1 July 1944)'. The 6-pounder had a big role in this battle and the book describes in great detail how they were handled. It is based on interviews with the British soldiers tha participated in this battle and gives a very intense and trustworthy account of a hectic battle For instance it tells about how the crews had been issued wih 'Sabot' (APDS) ammunition without proper instructions or training. As a result of this a lot of targets were missed because the guns sights were adjusted incorrectly. The flatter trajectory required the 'no range setting' at typical battle ranges of 400-500 yards, but crews kept setting the range scales as they were used to (page 126-127). Talking about missed oppertunities ! But in spite of this the 6-pounders managed to knock-out quite a lot of German AFV's in this battle, in one action one gun took out 5 AFV's. A lot of information about the British 6-pounder can be found on this link 6 Pounder Anti-Tank Gun Note how the production of both tank and towed 6-pounders fell from 1943 to 1944. The gun was clearly getting obsolecent.
