Also request time frame, Thanks
HOUSTON-
THE SIGNATURE IS DEWA NO KAMI SUKESHIGE. I COULD NOT FIND ANY INFORMATION ON THIS MAN IN "NIHONTO MEIKAN," WHICH IS THE MOST COMPLETE REFEENCE OF SWORDMAKER SIGNATURES. FROM THE NAKAGO ONLY, I WOULD GUESS THIS PIECE TO BE MID TO LATE 17TH CENTURY.

HOUSTON-
I FOUND THIS MAN IN ANOTHER REFEENCE. HIS MAIN WORK TIME WAS DURING THE KANBUN ERA, WHICH RAN FROM 1661-1673.
