I disagree.
From the limited pictures it shows the correct weight reducing modifications to the action and I suggest it is a correct No5 Action, but the barrel ............ ? (cannot tell)
India had quite a lot of No5's which got the 'cleansing' treatment and Indian add-ons.
Nothing wrong with it, it just has Indian history / service in addition to UK History. *
The shape of the body below the Rear sight is NOT the No4 shape, but it IS the No5 shape.
* based on the limited photographs.
