The Tortoise heavy assault tank (A39) was a British heavy assault gun design developed during the Second World War, but never put into mass production. It was developed for the task of clearing heavily fortified areas such as the Siegfried Line and as a result favoured armour protection over mobility.
I have the Operation Unthinkable boxed set containing the British and German tanks. The GF9 Operation Unthinkable boxed set, the British versus German, contains 17 tanks, two of which are the Tortoise heavy assault tank.
This is the GF9 finished model.
This the sprue.
Not too may parts. I think I will add some weight to the models.
