Frankly that is not realistic. Other than on rare occasions, no one can know where a BritishArmy rifle like yours has been. Over its career, your rifle may have been, for example, in the hands of: an Army Service Corps driver in France
during the Great War, an Infantryman in Palestine between the wars, or a Royal Artillery Gunner at Tobruk during the Second World War. On the other hand it may have been in the armoury of a school Cadet Corps for most if not all of of its life. We certainly had identical rifles in our armoury at school.
