The older Russ has a large turret ring that the FW turret slots into its basically a large disc about 5-6mm thick on the turret underside, the newer Russ has a much smaller turret ring so won't accept the FW turrets like the Annihilator unless you completely remove the disc and glue a bit of plastic tube or something similar to the turret to fit the smaller turret ring.

I have both the old and new style Leman Russ, a FW Vanquisher and a FW Executioner turret, FW Russ turrets fit the older style tank but wouldn't fit the newer Russ released a few years ago.
