Hello, all. New to the forum, and overall world of NBTHK sword interest.
I'd been eyeing eBay for a long time now, looking for a nice katana, and stumbled upon a tachi koshirae with a deerskin sheath with papers dating it to the Muromachi era.
I've spent hours researching this concept, and there's surprisingly little that I can find, and some of the information I acquired came from a thread on this site. In short, the skin sheaths, or shirizaya [misspelled in title], were used to protect the scabbard while on horseback and most mentions and the very few pictures that exist show bear or tiger skin/fur. When I bought this, the seller mentioned deerskin, but it seems much more likely to be bearskin based on color/length. Shocked that it's as in tact as it is. Anyway, figured I'd showcase it and get any other information from those much more informed than I.
Thank you, more pictures below.
