@Bombhead, that's one of my pictures. In fact I'm trying to draw this edition, but I can't find any informations of the rebuilding. I know for sure, when the three vessels were delivered in 1958, 1960 and 1960 they where very similar to the british. I've tried to search on indian sites, but besides they briefly mention the former Leopard Class they all write about the new Brahmaputra Class with the same names and pennant numbers
