Ken, I appreciate your response. I know I am not extremely knowledgeable in this area, but I don't get the idea these are fakes or replicas. I have had them for quite a long time. I don't know how long fakes have been common, but I think these may be older. Also, it seems as though a faker would have been more meticulous than to omit the mekugi, which is a pretty obvious piece. The one with the brown hilt also stands out as quite different, so I don't know what it might have been intended to replicate. The decorations on the scabbards are identical to each other, and they are slightly different from the pictures I have found, including yours. Th scroll work on mine is more open. I am still in a quandary as to what I have. Again, thank you so much for your time and effort in getting back to me, and thank you for the reference you provided.
