And now for something completely different the same. A man with three buttocks.
What’s interesting about doing a details-exact cover is that it’s like a studio documentary bit that never was - showing all the parts in the stew.

The new Robert plant album, carry fire or hang fire or whatever it was, that title track caused me to develop a whole new respect for Robert plant and a new appreciation for the music of led Zeppelin.

Dude! I was thinking about that exact Monty Python thing myself just in the last couple of days.
also, we need to brainstorm how to engineer the embouchure mechanism
for the trombone rifle.

That is m y favorite led zepplin album of all time.

I would handle the embouchure by putting a double compression fitting onto the horn section, removing the ferrule and nut from one side, inserting a rubber disc cut from scrap with a slit cut in it into the ferrule cavity, and linking it to whatever with flex. As this:
Compression fitting somewhat as below:

I could not have conjured up that idea myself. Rigidity of the rubber or neoprene, size of the opening, and the amount of pressure would all be variables. I guess first, I should find a sacrificial horn.

The size of various pieces would be dictated partly by the horn, and partly by the connection to the valve from the spray tank kit. You might end up with a “conversion” style compression coupling with a 3/8" tubing connection on one side and 5/8" on the other, or some such.
You might for testing purposes buy a cheap plastic vuvuzela until such time as you can source a suitable horn.
The rubber washer, I admit I don’t know an ideal thickness. My instinct would be to cut a scrap of ~1/8" rubber from something
and then progressively widen the slot to see what works best as a reed. I’d suggest radiator hose except that it’s fiber-reinforced and so rigid I don’t think it would “flap”. Red antimony
rubber like a toilet plunger or piece of gasket is probably about right.
In fairness, you might be able to blow-test a rubber disk with your own mouth to try some different sizes and designs of reed, though your mouth pressure would be lower than the tank and you might not have enough. Given that the spray tank drives a lot of the design (tubing, reed sizes, musket choice, musket stock modification, backpack mounting)
and is also conveniently pretty
cheap and would allow reed development
, it might be the first step.

I should note - my place of work has most of the things that this would require. If I find myself subject to being bored out of my mind here at work sometime soon, I might be able to do a reed size and materials test. No promise, but neither is it impossible.

Rubber disc. Are you thinking like innertube rubber?

I’d like to try and take you up on that. First, I need to find a garage sale trombone.

Might be too thin and flimsy
for a reed, might not, at least if of the bicycle kind
. My concern would be being able to keep it in place - it’s not very stiff, so the disc idea like I described might not
work exactly. A piece stretched over the end of the tube (not stretched very tightly) might still work, it would just be more involved.
I’m almost certain I remember something about an inner tube rubber noise maker in a 50's craft book back at the house, though I don’t remember details.
A tire patch of the disc kind might work, cut down.

I am by no means an expert on making musical instrument guns out of chemical sprayers and hardware store junk, but I may be the closest we’ve got.
