I have a feeling this is a WW2 Indian fighting knife presentation piece. I have a war time kukri just as pristine with slight wear to the scabbard. These are pics of Indian made ww2 fighting knives from "Ron Flook's British and commonwealth fighting knives" I am sure we are all familiar with presentation kukri and Fairbairn-Sykes commando knives. I think this is in that genre and as such a jolly good thing, if you like that sort of thing that is.
