Here is what I assume is a Seki stamp on the tang of my Ido Hidetoshi named blade. It does not look quite like what I have seen on other Seki blades. Is it,like other militaria I collect, a variation or does it mean something else? Forgive my ignorance but I do not regularly collect anything other than US items.

Thanks in advance for your help, Jerry

I have a WW II officer's sword that I need help with. I have scoured sites and have had no luck. Here are some pictures. Hope ya'll can help.
