WTT: Vintage Bass Guitars for sousaphone

[MartinMan]

Any bass doublers out there?

I have a few different WTB treads active on here, and rather than clutter things up by adding a trade option to each, I figured I'd post everything consolidated to here:

What I'm looking to trade:
-1960s Gretsch 6071 Bass (good condition, non original case,)
-1960s Kay electric bass (fair condition, no case)
-Fender/Squier Antigua Franken-P-Bass (excellent condition, Curtis Novack pickup, no case)
-JD Guitars custom, short scale fretless bass with DiMarzio PJ pickups

What I'm looking for:
-Fiberglass sousaphone with a medium/small bore (anything around .687" that isn't Jupiter) King, Olds/Reynolds, Martin, Holton, etc. Preferably 1960s or 70s vintage. I'd also be interested in a modern king copy such as JP or a Olds/Reynolds copy like Eastman. Or a misc. Chinese copy that is of decent quality.
-Jr. sized sousaphone. King/Cleveland, Olds, York, WM Frank, or modern examples like the IBI Olds Jr. Copy

Interested in trades or partial trades including any combination of the above instruments.

Located in Chicago, IL. Could ship but local pickup or driving to a central location is preferred.

Will edit soon to include a link to pictures. Feel free to PM for more info on the basses or for photos.

Don't forget that some early Pan Am's also had the .687 bore, in a Conn wrap. I have played one. Great horn for being 100 years old. Unfortunately, it is not mine to trade. Here is what it sounds like, with a Conn Helleberg mouthpiece:

PS - I practiced at home, then cut the track in one take.

Good to know, thanks for the heads up! I'll keep on the lookout for one.
