It looks like he is looking for an offer.

Pretty neat seeing a ferrule on the lower leadpipe below the neck receiver. Most after this had that as one piece, not two.

No goose neck or bits with this one. I asked.

I think a modern Conn neck could be retrofitted rather easily. My 1902 version is 0.734" bore, and a 20K neck and bits fits and works well.

That's not a problem. Unless you really need that Victorian-era rounded bits, the Art-deco era ones work just fine. Or get a new set, just the same, but less quality.
