Mei translation and or authentication

I recently bought this wakizashi and when I oiled the blade I was interested in the kanji to see what it was I had, I was surprised at what I found and I am unsure what it is since I cannot seem to recognise any of it. I would be really grateful if any of you folk could tell me what this means if anything. , ..

thanks guys, I was stumped and was expecting a lot more in the way of writing, and the figures seem to have been individually punched in making it really hard to make out, I have looked at other swords and the inscriptions seem much clearer and a touch easier to get a handle on.
