No! it is not so, the BEHEL acquired the license of the Compact 76/62 in 1995, so those made in India are of a different version to the one supplied to the Navy of Myanmar.
I think the compact 76/62 available to Burmese, come from military surplus equipment market, as only South Africa and Israel had that kind of naval cannon is likely that with a kind of triangular trade in some way, during arms embargo, these compact 76/62 from decommissioned ships, arrived in Myanmar.
