Much of the loot has owners other than governments - descendants of the people from whom it was stolen in the first place, insurance companies that paid out on losses, etc. That is why they’d ask for their 10%. Take their cut, run like heck and let everyone else fight it out in court.
I want to know where and how the train was hidden that it was not found for almost 70 years!
My question too. I have always wondered about how much treasure is out there, from pirates like Captain Kidd to the Nazis, hell the knights Templar treasure could be out there too and lets not forgot about all the ships carrying gold from the new world.
Easy peasey if a spur branched off a nearby rail main line. An enterprising officer and compatriots arranged for retirement, it being common knowledge in some circles, the end was near. The evidence of the spur and the tunnel entry into an underground war materials production site was obliterated. If needed, destroy a mock shipment to cover inquiries about the loss. Remove witnesses.
