Tropical Panzer transport collar tabs, ORIGINAL?

I was offered these.
Construction looks correct, but can’t find any references.
Anyone seen this type before?

Thank you

Those are absolutely bizarre. Never seen anything like those before. But I agree that the construction is ominously period. I really hope someone knows what they’re for.

I don't like the buckram, nor do I like the way the ends of the piping are finished.
