Many of them seem to have been shipped to India.

An interesting twist is that post WW2, Indian troops, apparently many toting MK V rifles, went to "Frenchicon Indo-China" to deal with the surrender / repatriation of thousands of Japaneseicon troops. Some of these Mk Vs seem to have been "mislaid" and ended up in the hands of Ho Chi Minh's 'Viet Minh" troops. There are a few (probably posed") photos of them "in the wild" in those parts, in the hands of suitably grim-looking Viets. Probably used for drill and propaganda purposes because of the limited availability of .303 ammo and appropriate spare parts, until they fell to bits and were scrapped
