Folding, "Portable" Outside Horn?

[donniej]

I'm working on building my "ultimate" portable disc machine. The last detail is an outside horn which is easy to store and transport. Does anyone have any info on horns built during their era that were meant to be collapsible? Design and construction ideas are also welcome.

Thank you.

Here's an interesting one, which uses a draw-string to collapse the horn:

Probably not quite what you had in mind, but the Polly Portable aka the Brunswick Parisian aka the Guiniphone was a portable that use a folding paper cone as a horn. Videos on YouTube, and some pics here of one I bought recently:
