Hi there, I bought a yari with with original koshirae in an auction, without further description. The menuki pin was missing but the tang was badly stuck in the wood. After many attempts I managed to get the blade out without damaging the wood. The blade is about one shaku. And I think it might be before 1600. Unfortunately the mei is not easy to read. Maybe someone has an idea. I am happy and thankful for any assistance. Greetings Marc
