If I recall correctly, stories of this Panther surfaced some 20 years ago. I believe it is one of the Post War production units built for the British Army and the gentleman that owns it now bought it in England when it was disposed of there , shipped it back to Germany and fully restored it.

Probably quite legally demilled 20 years ago, but he his likely going to be raked over the coals for not keeping the demill requirements up to date.
