My local museum, in rural Australia, has 2 swords donated by someone. One is obviously the type a soldier would wear all the time. The other is ornate, with gold inlays on the wrap, and ray skin saya. The tang is so rusted I can't read any inscriptions. I see this forum mocks amateurs restoring swords, and I understand that, but rust will claim it. These blades will sit in a display case. When I removed the tsuka that was the first time since the war. I would love someone to take an interest in advising me what to do, to preserve them, and give a historical context. Can send lots more photos if you give me a contact. Thanks.
