George Wostenholm I*XL NIMROD Knife

This lovely knife belonged to an uncle of mine and traveled a fair bit of the world in the late seventies. I remember him coming back from an African hunting safari and having all these different antelope heads stuffed, something he now sort of regrets in his later years. He sold them all a few years after the event. He gave me the knife recently and it will go with the 'NFS' treasures like my G G,dad's endless sash clamp.
After a little research I've found this can be dated 'after 1945'
