Found this sword at my grandfathers house while cleaning. I’ve attached the letter that we found with it. I know nothing about swords but am very interested in learning the history and value of this sword as it’s been in our family for ages. I’m also curious what the process for selling something like this would be. Will probably keep it for its sentimental value, but curious nonetheless. Any and all help is greatly appreciated. Very eager to learn more!
