Here are my humble shishi fittings for you to see Mr hennick, the menuki are a bit strange, the metal is very tin and the middle support is gone, maybe these were used as a cigaret pouch clasps at some point? im not certain about the quality... but the metal looks like brass. I do not know much about the tsuba but I love the it alot.

The tsuba is wakizashi sized, i have shown it here in the past a while ago, excuse the redundancy if youve already seen it.
