Talwar with seperate, riveted tang

[ihutch1]

I recently bought a bundle of completely encrusted, munition quality talwars from India. I disassembled them for cleaning and inspection and found that one had a tang which is riveted to the blade. It is a piece of metal folded into a 'V' sandwiching the base of the blade, and riveted through. It is free to pivot to some degree in both directions.

Have you encountered anything like this before?

My first assumption was that it must be a repair (hard to say definitively) and certainly inferior to a monolithic tang but, probably only coincidentally, it proved to be the hardest blade to extract from the hilt.
