Have you found a method to directly covert the grid coordinates to latitude and longitude? I've gone through publications like this: https://s3.eu-west-2.amazonaws.com/redatlas/TM30-548_1958.pdf trying to find a coherent solution that matches the maps you are referencing, but the offset from meridian and equator, or even the corner of one of the 1:200000 pages, does not seem to line up with those.
