I agree the handle on this knife is super weird. I have a hard time believing it is original. Agree that the tang not being tapered is unusual and suggests it's not that old. In the end, I don't see much special about this knife, and see a lot of drawbacks. If you are hoping for someone to tell you that you found a rare and valuable piece, I think you'll be disappointed.
Moving forward I'd suggest that you limit your questions about a single knife to one thread. You can always try replying to the thread to bump it in the hopes of getting more attention. Creating multiple posts with essentially the same question on the same knife isn't going to win you any friends or garner any better responses than you've already gotten.
