I have the Operation Unthinkable boxed set containing the American and Soviet tanks. The GF9 Operation Unthinkable boxed set, the American versus Soviet, contains 21 tanks. Two of these are the T28 Super Heavy Tank.
The T28 super-heavy tank was an American super-heavy tank/assault gun designed for the United States Army during World War II. It was originally designed to break through German defenses of the Siegfried Line and was later considered as a possible participant in the planned invasion of the Japanese mainland.
This is the GF9 finished model.
This is the sprue.
