Hey guys,   A recent acquisition to collection and I felt it deserved to be shared. It's a Tokubetsu Kaga koshirae, original to the sword, resided in the private collection of an armor collector in Japan for over 50 years. Sword it was made for is a Naokatsu, made in Echigo. I would appreciate it if you could share additional information, as I have only just started studying it yesterday.    Thanks
