I think the question though, should be were any of those factories producing 303 during the war, or did they change over the production lines to other calibers? A machine making 303 could be easily switched to running other rifle cartridges. Were the occupied factories engaged in production of ammunition for 7.5mm or 8mm Frenchicon weapons? Or ammunition for the Italians? Were the machines shipped to Germanyicon to be run in a more loyal factory? My understanding is that the number of serviceable .303 rifles captured was very low, as many had been disabled by the expedient of breaking the striker and loosing the bolt head. Would the handful remaining have been worth making ammunition for in excess of what was captured?
