Hello gentlemen   I did a little bit of shopping today and acquired 3 tsuba. As usual quite cheap. All pictures are from auc description. That's all I have.  1. This one I got to replace trashed tsuba on my Satsuma Rebellion sword.  Is the cherry blossom a Mon? I believe this cut through design called sukashi?   2. I believe we have here ship sails, masts. Is the design on the bottom represent mist?  Can I also get help with the signature please?
