This is either a Army parade or Police saber. I've always read police swords were the ones with a five pedal sakura blossom, where as the army was a blossom of ten the pedal type. If I'm not mistaken, Fuller and Gregory ( Military Swords of Japan) , are showing the one in the photo's below as army. Would anyone happen to know exactly which the sword  is ?   Thanks in advance,   Dave M.
