E/b concertina...help?

[Piper_Mann]

I recently bought a concertina on ebay from some people who knew nothing about it. I knew it was an anglo, but I couldn't find what key it was in. Hoping for a C/G, I went for it.

When it got here, I went to work fixing it and getting it set up, and when all that was done, I set down to find out what key it was in. It appears to be in E/B, or Eb/Bb, I can't tell because some of the reeds are out of tune.

So I was hoping someone could tell me what to do with it. Help?
