3 inch M5
Originally I needed 4 of these guns for the Mortain scenario. After that I realized they would be useful for other scenarios as well.
The gun barrel was made from two pieces of a small wood dowel on top of 3mm wide card laminated to get the right looking thickness. The gun carriage was made from balsa and has paper tires[1] from the PTA Kubelwagon.
25mm SA-L mle 1934
The French Hotchkiss factory produced these guns in the 1930's. During the battle for France they were used by the French to good effect against the Panzers. The flash hiders made them hard to spot in concealment. One account says a hidden gun killed 7 panzers (3 Pz II and 4 Pz III) before running out of ammo and being discovered.[6]
I designed this one in paper using Inkscape and some line drawings from a foreign encyclopedia[8]. I am very pleased with how it came out.
47mm SA mle 1937 (APX)
At some point the French realized that they needed a better anti-tank gun and wrote specifications that resulted in a gun that was very good for its time.[10] Unfortunately there were not enough built before the war started. From what I can tell, it used a similar round to the one in the S-35 and B1 Bis, but the barrel on this gun was much longer and gave a better performance.
