I hope you don't mind. I lightened your picture a bit so we could see the detail better. It seems to me a very nice bolo, with a hilt style I have not seen before. Hopefully the experts will stop by and comment. It's as least as old as WWII, maybe older. I'd be careful about chopping with it. If you need a blade to use, I'd be glad to trade you a nice hatchet for it.
Thanks for sharing!
