where could I see larger photo's of your image's....the sword tassel look's like a military tassel....the sword and handle look longer than a Katana...maybe a Tachi sword...the sword does not have military fitting's...tsuba,habaki,menuki and fuchi and kashira all show great age and are civilian made...I can't see the Saya clearly...but it does appear to be a military Saya, after the end of WW2 all Japanese Officer's were required to surrender their sword's to the occupying force's.
