T-51F help....again....

[hamerhead]

As you know, I picked up what seems to be a fairly rare Nashville(?) T-51F From Dave's: 

Great little guitar. Everything appeared to be original, except for the added mini toggle, possibly the pots, and the associated nasty wiring.

I did a quicky rewire to make it functional from stuff I had laying around (it's not pretty), but now would really like to put it back to the way it came out of the factory.

The problem is, I don't know what that is. The Fishman and middle pickup takes it out of the 'normal' Tele realm and I don't know where to even begin looking.

Help!

...here we go again....

I'm sure there are fans here that know.

This is the best I can do.

From this thread:

It appears stock wiring omitted the Tone control to maintain the standard two-knob layout and provide a volume control for the Piezo.

Logically then, the Piezo volume would come after the switch, wired as a Blender knob. ETA:? That was posted as a statement whereas it should have been posted as a theory - I have no idea.

I'd be really tempted to go with a stacked pot on the Tone control to keep a Tone for the electric pickups and a Volume for the piezo.

Just found this photo of a "Dead Mint" example and it has the same mini switch:

Could it be, rather than a blend knob, the piezo circuit is enabled by the mini switch? I hadn't taken that possibility into account due to the comment above of "added mini toggle."

Found this thread that provides even more information: 

Sorry to be bombarding the thread, but I have a very technical email I am trying to compose and the distraction is helpful for getting my conscious brain out of the way of attempted expression (or something like that). 🤔

Nashville's with piezo have a stacked pot. Sure I had a wiring diagram way back: I'll look for it but don't build your hopes up: my backup drive fizzed out on me and as things are I can get nothing off of it...

It had 2 mini toggles when I got it - 1 looked stock (not sure if it was), the other kinda jammed in along side it. My pea brain couldn't comprehend it all, as neither functioned in a way that made sense to me. Which is why I was wondering what the stock configuration was.

Not sure about a blend control. I mean I get it, but the separate volume on the Fishman should accomplish the same thing, no? 

If I can't find out how it came from Hamer, I'd go with a stacked pot for the normal pickups, a regular volume control for the Fishman, and no blend/mini switches at all. The cleaner the better.

Who from the factory might have such knowledge? Who was their wiring guy? Is there anyone I can ask?
