I have been a long-time buyer of Japanese swords, mainly at local gunshows and militaria shows. I sometimes picked up a nice sword with a damaged or missing scabbard, and then I would look on ebay for parts to repair them. About 5 years or more ago, I bought a group of three empty scabbards from a seller on ebay. Two were leather-covered WW2 vintage field scabbards, and one was just a bare black-laquered wood scabbard. They came to me in a triangular cardboard shipping box.
Why I ask is this: Tonight I was seeing if a sword I purchased on saturday at a local show might fit in one of these scabbards. The habaki was tight, and when I withdrew the sword, it pulled the thin wood liner out with it. Crammed down at the bottom was a business card from a US Navy Rear Admiral, with handwritten notes on it detailing a very interesting history of the sword that scabbard once held. This sword had been captured in one of the last surface actions by the US Navy in WW2, and had been presented to Admiral E J King. Here is the card, and the scabbard it was in:
Hopefully, someone here might recognize this scabbard, or at least remember selling three empty ones as a lot on ebay. I would be able to tell if that sellers ebay name appeared in my feedback. It would be very exciting to track that sword down and provide a fascinating history for it. According to the card, the sword was captured Aug 20,1945 by a Lt Swentzel, US Navy, who was commanding a Chinese junk with both American sailors and Chinese guerrillas on board, when they were attacked by a Japanese war junk with 83 men on board. In a three hour running battle n. of Haimen, They captured the junk, and this sword was surrendered by the captain. This action is detailed in the Official Chronology of the US Navy in WW2.
