Here is a Fender MIM, I believe but could be wrong but am pretty sure it is Fender made, '51 P-bass body. It has a coat of primer on it but probably needs some sanding and then reprimed and painted. Ash. $80 plus shipping.
neck pocket is 2.5" x 3.75" at longest points. I believe it fits a Fender neck. $80 not including shipping. Give me your zip code and I'll give you a price.
The neck pocket does not look like a square route. I believe that would make it not an actual fender body but I could be wrong about that. Either way a fender neck with square heel will not work with it. (Unless I am looking at it wrong)
