The 'restoration' is on hold as they have other things to concentrate on.
A ww1 tank, for instance.
They are not restoring this vehicle anyway. All they will eventually do, is put all the parts back together and then use it as a ' training' aid for US service personel.
It is destined to remain unavailable for viewing by the public and is not going to be 'restored' , nor will it be a runner.
