Mongolian Box Prison

The swastika symbol has been a religious symbol in that part of the world for millenia. It's not clear why it would be inscribed on this prison box. Perhaps it was already on the wood used to construct the box. There's a good article about the symbol's history that includes its adoption by far-right nationalist movements in the early 20th century. https://www.ushmm.org/wlc/en/article.php?ModuleId=10007453

I've always understood that the National Socialist German Workers’ Party was a far-left organization.

Left, Right -- it doesn't make a difference. When they get that far extreme, they meet in the middle. What DOES matter is that both Nazis and Communists were totalitarian.

Since the Nazi Party got major support from -- and helped contribute to the wealth of -- big industrialists, I would assume they would be classified as "Right-Wing".

The "hot box" has been a familiar means of punishment for probably as long as humans have been meting out punishment.

RobK: it was a far-right organisation which adopted a veneer of supporting the "honest working man" because of the votes it drew.

Remind you of someone recenty?

But the Nazis were opposed to all the Jewish business owners and capitalism, and wanted the government to control everything and were opposed to basic individual rights, which sounds left-wing to me.
