Here is what I have to offer:
-A 1927 Buescher jumbo 3v sousaphone silver/gold wash, original neck & bits, and og mouthpiece; purchased from Dillon
Music. The valves were recently rebuilt by Dan Oberloh (as of august 2024) and they work great. Pictures below!
What I'm looking for (ambitiously):
-Conn/King Jumbo (ideally same kind of finish; heavy tarnish is not an issue as long as the material underneath is good) and however unlikely with 4
valves; although not a necessarily a requirement.
Explanation: From what I'm told (because I've never played any jumbo other than this one) is that the Bueschers play better than the others(mostly because it's smaller than the conns or kings), but I figure if I'm gunna have a sousa this big I might as well aim for a conn or king. In idea I would be trading a horn with good valves for one that looks similarly good but with 4 more worn valves.
Other things I might trade for; One of those king pit tubas, or however unlikely one of those jumbo conn raincatchers
send PMs thanks!

I'm located in Louisiana but willing to drive a long ways
