No idea but welcome. Pictures?
Any idea of "condition"? If it were a factory second kind of thing I'd guess Guild because no oceans were involved to get the body to you, but all bets are off it is a previous project that started with disassembling an existing bass.
Just because, below is my favorite Frankenbass with Guild parts.
My recollection is Leo Quan (of BadA$$ bridge fame) built it from a 60's JetStar neck, a body of his own devising and a couple Hagstrom Bisonics that Jack Casady had stashed away. You don't really try and play it sitting down :-)
