Perhaps the name itself at the bottom is a form of Sairen (西蓮)?

[Jussi Ekholm]

I think Ray is correct, I would dare to guess the mei would read 談議所西蓮 - Dangisho Sairen, and in your picture the last 4 kanji are seen. So far I have only 3 tachi with Dangisho mei in my references, I know there might be few more but those are the surviving ones I have been able to find.
