Without 10 or so detailed pix, preferably posted to tje tread, we can’t help you. Be sure to include close-ups inside annd outside the pot.

Im new to the forum and still learning the jpeg upload method. Someone messaged me identifying the pot as Leedy. I checked around and can confirm thats correct. It's a dead match for a Leedy Solo Tone. The neck is still a big mystery tho. The Gibson inlay work and aging on the finish appears authentic when I compare it to my other legit Gibsons. The truss rod confuses me though. There is no truss rod cover, but there is a barely visible hairline rectangle running down the back of the neck that im assuming was cut out to fit some sort of truss rod in. I've never heard of such a thing. The neck is made from a single piece of wood. Here are some pics.

Leedy pot matched to a 20’s TB 4 neck.

If done well, probably a nice sounding player.

Your original thoughts are pretty spot on.

Question out of curiosity. Why no Mastertone block on the neck?
Is the neck original Gibson or a copy?

Hardly anyone would be making Gibson repro tenor necks, I think. This neck looks like MAYBE a style 3 maple neck with a replacement Bella Voce fingerboard. Bella Voce boards did not have the MASTERTONE block. The hearts and flowers peghead is a puzzle, normally not seen on a Style 3 neck, but one can't say "never".

The side binding on the neck would normally have received white/black/white binding for a higher model like a 4 or Bella Voce. Only a Style 3 had plain white binding.

The long rectangle joint in the back of the neck, certainly expertly done, is a mystery to me. Truss rods are normally installed and replaced by removing the fingerboard, which this neck has experienced at least once it appears.

Of course the neck could have been a factory "floor sweep" from the late 1930s or 1940s.   There are several examples of Style 3s from the early/mid 1930s of Bella Voce peghead facings on Style 3s.

More photos are needed of course.

FWIW, I have what looks to be a Saga/Golden Gate five-string neck that has Bella Voce fretboard inlay and hearts and flowers peghead inlay on a fiddle cut peghead. It had a blank block at 21st fret and, in what always looks to me to be a sign of Golden Gate, a side position dot at the fret of the block.

Bought it on eBay ages ago in what was described as a sale by someone who had acquired lots of repair parts from a music shop that was closing. Right after I bouhgt mine, the seller put up another neck: hearts and flowers fretboard with Bella Voce peghead.

If this neck is original Gibson, why doesn't it have a truss rod access
on the peghead?
