All heavy guns (2x sFH-18 & 1x soviet 203mm) are scratchbuilt. Paks are modified with metal barrel (and multi-part muzzle breaks made from brass and heat-shrink tubing). All are done to "fine" standards, and the 203mm is an "uber-model" (extra-fine detail, small self-contained diorama).
Germans are set on "muddy" bases, Soviet 203mm in snow. All 3 heavy guns have the apporopriate ruts in the ground from the wheels, and recoil from the spades. Snowed base has some kicked up mud mixed in with the snow. 203mm also includes shell loading carts, shell hoist (in use), and breech rammer. Ammo for all guns is split ammo (seperate powder charges and warheads). sFH powder charges are in brass cartridges, 203mm are cloth-bound powder bags.
