Hi guys i'm new here and don't know if I have posted in the right Place

I have just bought a Richwood re 125 and after some research I found a lot of people talking about the pre-lawsuit version being better than the post lawsuit version but my question is. How do I find out if mine is the pre or post lawsuit version. I have looked on the guitar but cannot find a serial number so I can't check it that way

Thanks in advance
