This is a patch for the US Navy's Black Knights 154. I bought it as a spare for an MA-1 jacket, but I don't think I'll be using it, so I'm putting it up for sale. If you'd like, I can include adhesive-backed hook-and-loop fasteners (Velcro, white/black) for an additional 100 yen. Please let me know if you'd like them. Thank you.
