1670? As far as I'm aware, there were two charters under Charles II: 1661 and 1683. Unless another was a very special dispensation, or a local one, nothing of 1670 is mentioned that I see. Page 11 of V. D. Mahajan's British Rule in India and After (13th ed., 1980) seeks to give the summaries of each charter, what it permitted in 1661 (basically a resumption of powers originally given in 1609, namely commissioning its own officers, building forts and deploying ships and security forces of its own to protect them, and giving the Governor and Council judicial functions (including punishment). 1683 was newer, and made the Company virtually sovereign, with power over war and peace, the right to levy for a larger standing military, and regular courts. I don't see any mention of 1670 in print. The relevant page of John Riddick's *The History of British India: A Chronology" (2006) puts nothing specific in that year other than a shift in the focus of trade. As 1686 and 1689 modifications are after Charles II's death, I am not considering those as candidates. So no, it doesn't look like there is one for 1670, and they may be thinking of 1683. The Hudson Bay Company, itself very powerful among English trading companies, started operations in 1670, but that would be a geographically strange mixup to make.
