Hi Bass Friends, I need some help with this one!
For sale/trade is this very likely genuine Fender American Standard Jazz Bass body from 2015, but there are things about it that give pause to a non-expert in Fender basses such as myself. I had purchased this lovely sunburst Jazz bass body from a very nice and reputable TBer who I'm certain is completely genuine and felt confident in the body being the real deal. That said, if anyone can comfort my lingering worries by definitively verifying the following related details in any way after reading my thoughts below, I'd greatly appreciate it!
I'm just wanting to be super duper certain as I put it up for sale, and I have priced it low enough to still be worth your while even if anything about it ends up being suspect! 
First of all, I'm not informed enough to know for sure what the markings in the neck pocket signify. Are they definitively Fender markings, and what do they mean?
Second, the output of the pickups is quite low. I'm not certain if they are Fender Custom Shop '60s pickups, although I have no other reason other than low output to question this. Again, they probably are exactly that, but I just don't have the knowledge to know for certain. It has the Fender tone, but with low output which requires significantly more oomph from an amp than I thought it would. Also, when favoring one pickup or another, the hum is loud. I haven't yet had my tech look at its pickups or pots, but I was told that its pots are CTS and that it has vintage cloth wiring, and I have no reason to question that.
Third, the through-body stringing option is consistent with the real deal, but I'm not certain if any alternatives exist out there with this same feature, so I wonder if that's a definitively identifying feature.
I'm located in Scranton, PA and my zip code is 18504. If you can get together in person, please kindly let me know so that we can connect. Feel free to share your thoughts and expertise, offer trades (+/- $$), or even just talk with me about "The Office" if you'd like.
A sale is most welcome, but old, heavy, thick and wide Warmoth necks always induce my Pavlovian response! Other trade possibilities can also certainly pique my interest, so please feel free to reach out.
An in-person transaction would be fantastic, but I can ship it if distance makes connecting in person simply implausible! We can do cash, Paypal F&F, or even Venmo if we must.
We'll figure out those details together when we reach that point... 
As always, I wish you a wonderful day and night, filled with amazing bass tone!
