Mysterious Buck?

[dangerousdave]

Can anyone tell me what buck knife this is? I thought it may be from the 500 series but its not. It looks similar to the buck prince but it is missing the ridge that is at the bottom of the blade. I know this is a third party modified buck but i am wondering what the original buck is call?
