Chargers and Bandoleers.
Definitely a repack.
The Green printed label is typical of British (and Empire) manufacture, this particular one of British make, for "Cordite mark VII"ammo. The actual factory indicator (same as headstamp) and date of "packing" of the lot would be rubber stamped over the Green Label ( as in "31-12-43 RG", usually in purple or black ink.
H3282 is the design number of the label, the ^ is the "Broad Arrow" and "ISAA" is "Inspectorate of Small Arms Ammunition", the British Organisation which does the QA on all SAA.
The repacking could have been done by GSA, or it could have been done by Interarms, who would have acquired the ammo from the British Government.
This ammo is of Surplus of the 1960s time period, when Britain divested itself of humungous quantites of Rifles and ammo to Interarms.
