I just keep thinking of all the work involved to recreate all the special components to make these. Even if someone made 10 of them, 10 x 5k each=$50k. There is no way you could make all these special components fit them together and age them for that. Just look at the pommel, the swas's were inserted to very close tolerances. You don't just do that in your basement. You need all the right tools. Think about that blade, a special length, forged and plated. You have to create the logo in hardened steel and press it into the blade.
I worked in a tool shop for years and trust me the costs of such a project is way up there.
Maybe I'm wrong but I just don't see such a venture as profitable.
