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, three of which are the Panzer IV/70.
The Panzer IV/70, was a German tank destroyer based on the Panzer IV chassis, it was armed with the 7.5 cm Pak 42 L/70.
This is the GF9 finished model.
This is the sprue.
