The Converted Mark II is not illegal at all. The conversions were done within the military in the early 1920s (I will post something in on other thread on this). As John explained in his later post there was some possible 'local' manufacture of Mills type grenades by a revolutionary group which puts another Indian grenade on the table. The official conversion and the 'revolutionary' grenade are not likely to be connected except by the coincidences of time period and country of origin.Thanks Bonnex!
And why would that be an illegal copy???
