Jerry Olivier? I think he signs his though, or is that a stylized "P".

no help whatsoever
Could be an older Phillippi they just used a P in the early days. If you can post pictures of the whole cue it might help.
I second OB, with someone carving that logo in. Looks too sloppy to be a cue maker's mark. I can see the OB shaft being sold before you got the cue if there was not one with it.
