Grey/Reinhard/et al-
Thank you for taking the time to look this over. Hopefully, the attached photo of the area that appears to have a signature is a little better quality-- I'll be the first to admit my shortcomings as a photographer. I tossed a penny into the shot to give some scale cues. A little more information on the sword: Overall assembled length: 37-1/4" (94.615cm) - Blade length: (from tsuba to tip) 27-1/4" (69.215cm).
The only "papers" on the sword that I possess are those associated with the U.S. War Department allowing a returning "Intelligence Officer" to bring the sword back home with him, "...[p]ursuant to provisions of Section VI, War Department Circular No. 155, 28 May 1945, as amended by Section VIII, War Department Circular 267, 1945..." They simply describe the sword as being "1 ea. Japanese Samurai Sword w/Scabbard." A pretty cool nostalgic document, but not much help as far as knowing anything interesting about the "1 ea. Japanese Samurai Sword..." :-)
Thank you all in advance for your help.
