Rick, Ian, I thank you both.
You confirm my thoughts of a bayonet. I was unaware of the British patterns however, and only knew the French ones

. It seems many countries adopted this yataghan-type blade.
Thanks for the link Ian, it's quite helpful...I'll start my own research into these bayonets as well, they're damn beautiful I think.
Now why would anyone rehilt these in yataghan fashion? Was this a common practice at some point, or is it just to deceive unweary buyers?
Regards,
Emanuel
