Russian T-28
German Panzer IV/70 (A)
1950's Russian cruiser Czkalow
T-28 is expensive, but it has:
• completely equipped engine compartment;
• full inside detalization of all the towers;
• gun moving in a vertical plane;
• all the towers rotating;
• opening tower hatches;
• opening engineer-driver hatch;
• opening engineer-driver viewfinder;
• opening access hatches to the engine and fan;
• opening lockers on the body;
• movable fan;
• rotating all wheels;
• movable wheel carriages;
• track either as a ribbon or with individual links;
• attractive, not very common, three-color spotty camouflage.
It's fourth T-28 model that hits Polish shelves, but it's the most detailed of all of them.
