			Hi Guys, 
		
		
		
		
		
		
		
	I have been unable to ID one of the arsenal marks in the fuchi of one of my shin gunto WWII katanas. It's the one on the right, an ovoid shape with a center X and two symbols resembling a C and an U on the sides, see pic.. Any ideas? Thx Manuel Luis

			Hi Rich, 
		
		
		
		
		
		
		
	The one beside the Accountability number on the blade is also Tokyo's Koishikawa Fuchi has three Arsenal seals: 1. Cannon-balls (Kokura and Koishikawa), 2. pre-1936 Koishikawa, and 3. Unknown . This makes it probably of 1934 or 35' vintage. The clincher is the third one. If you find anything, kindly let me know. Best regards, and Merry Xmas to you and yours. Manuel  |
