One thing to note about the Formations Stuart conversions is that they do not correct the fundamental flaws of the Academy or Tamiys kits. They improve those kits, but several of the basic flaws are still there. For instance, teh turret ring on the Academy and Tamiya kits is too small by almost 1/8" and the Academy turrets stick out over the edge of the armoured guard around the turret ring. In real life the angled base of the turret pretty much blends right into the angle of the guard around the turret ring, there is no overhang. Generally the Formations site has clearly noted this fact, but just be sure to read it before buying. Paul
