If I gold-plate the instrument, is it possible to keep certain parts silver-plated (since silver-plating is first)? For example, the things on the valve slides and the 'Mirafone' ring around the bell.
The only benefit from silver-plating is that it looks better, and that is a matter of taste only. Any other differences will are related to other differences, or are myth and lore.
You have given a new case study in the phrase "gilding the lily". Gold plating on a Miraphone would cost more than the instrument, and it would wear quickly. The gold alone would cost close to $3000, plus the cost of plating and preparation. I think you're looking at between $4000 and $5000, even if you could find a place to do it.
And to do it right would suggest silver-plating it first, so you can probably add to my amount.
Both require the same preparation as lacquer, which is a complete buff job.
By the way, the silver-looking bits on a Miraphone are solid nickel-silver, not silver-plated. If you had the horn plated, you would definitely want to plate over those parts. They need lacquer to keep from eventually turning gray.
Silver does tarnish if it is exposed to air. You can prevent that for a long time by keeping it sealed in its case when not in use.
Were it me, I would just remove the remaining lacquer, polish it out once, and let it age naturally.
I'm also thinking of a Dillon adjustable gap receiver. I have read a bit on old TubeNet about it. "They" say that it is supposed to help change the resonance and articulation of the instrument, but others say that it would help me to fit my American shank mouthpiece into the European leadpipe. If it can do both then I will be happier. Has anybody tried to uninstall one of these?
The AGR is used to adjust the gap between the end of the mouthpiece shank and the joint between the receiver and the leadpipe. It's not used to accommodate different shank tapers. But an American-shank mouthpiece should fit fine in a Miraphone--My Conn Helleberg fits fine in my 186. The euro-shanked Laskey does not fit as well in the Miraphone (though it's acceptable), but it's perfect in the Holton. Try it before you decide it doesn't fit. I would rather replace the mourhpiece or receiver outright than spend more for an AGR, unless it's the qualities of the AGR that I want.
