The front tracks and weapons of the JN-129. Each of the five smaller turrets is armed with a 90-mm gun and will fit in my KV-chassis like all my other tank turrets (though I don't see anyone doing that). The large turret will fit only in the JN-129 hull and is armed with a 250-mm main gun. Please note when assembling that the drive wheels are in the centre of the tank - therefore the two sets of tracks are not pointing in the same direction, they are facing each other. In addition, there is nothing to keep the front section from falling out if you pick the model up save the tight fit of the mating surfaces. I will probably add a key-type retainer in the near future.
