About a week ago I bought an old vintage kingston acoustic guitar. I have removed the strings four days ago and I need some ideals of what kind of string to put back on it. I don't know what kind of strings where on it before to me they looked like electric guitar strings. So your guess is as good as mine Should I put some light strings or something like that on it? I just don't want damage the frets or put to much stress on the body and neck I don't want the neck to warp. Have I left it without strings for to long?

Also I still don't know the model or age of this kinston. Can someone help me identify this guitar?
