Ron, are you going to take the lid off, or can you establish how many gears? It is a very short box, so maybe it's just a fwd/rev. box, and ran a separate gear box.
Hanno, what power unit drove this tank? do you have any info on the drive line?
Id guess that the big diff is fairly simple inside and probably has a couple of brakes inside as opposed to steering clutches, which would make the steering a bit crude and jerky.
