This is super rare. So super rare that it is highly likely that Fender produced the neck in a small batch in 1971 only to join it with a body built in 1974 to a complete instrument in 1976. Sounds plausible to me and it is what the dates on the parts tell us. Most importantly though: the bass sounds huge, weighs nothing and plays like a dream since the fingerboard has been pro leveled in our shop. OHSC is even included! Talk about rare huh? Original 70-s lefthanded P case, I kid you not.
