Musashi had her 15cm wing mount guns removed in April of 1944, and had 3 posts placed intended for extra 127mm guns on either side. Unlike the Yamato, these spots were instead filled with 3 triple 25mm mounts on either side. aditional portholes were closed, numbers 8 and 7 searchlights were also replaced with rocket launchers, and type 13 radar attached to her mast. total AA armament brought to 35 triple 25mm mounts and 24 25mm single mounts. Please not that the configuration of Musashi was poorly documented, so this is the best rendition of her in 1944 that I could produce:
