I NEED TO DO SOME RESEARCH ON THIS NAME AS IT MAY BE THAT OF AN UNLISTED SWORDSMITH WHO WORKED IN THE LATE EDO PERIOD. WITHOUT BETTER PICTURES OF THE BLADE IN IT'S ENTIRETY, THE SIGNATURE IS ALL WE CAN GO ON. THE SHAPE OF THE NAKAGO AND STYLE OF SIGNATURE ARE NOT REMINISCENT OF A SHOWA PERIOD BLADE. THE PAINT IS APPLIED TO THE NAKAGO TO IDENTIFY THE BLADE WITH IT'S MILITARY MOUNTS AS THEY ARE MANUFACTURED. IT IS NOT INDICITIVE THAT THE BLADE IS MODERN. MY GUESS IS THIS IS A HAND MADE BLADE BY A LATE EDO PERIOD SWORDSMITH OR EARLY TAISHO MAN. PLEASE GIVE ME OVERALL PICTURES OF THE BLADE ALONG WITH A MEASUREMENT OF THE CUTTING EDGE.
