In a small room in the Godrej Archives, located in Plant 19A of the group's sprawling campus in Vikhroli, Mumbai, a young archivist is delicately cleaning a bunch of letters with a soft brush.

Dating from the late 1990s, the letters are from the Indian Space Research Organisation (ISRO) to Godrej & Boyce Manufacturing Company, which then had the contract to manufacture of engines for the first Polar Satellite Launch Vehical (PSLV). The letters have recently been discovered gathering dust in the company's process equipment division and they have been deemed to be of some historic significance.
