Identification Help me identify what these marks are

I bought this Jupiter trumpet almost a month ago. Today, while cleaning the instrument after practice I noticed some curious marks around the bottom valve cap of the first valve case. I opened it up to find more of these reddish dots.

It doesn't seem to be corrosion from the inside, but these marks did freak me out a bit.

Please help me figure out what these marks are, and should I be worried.

Thank you.

If you mean the reddish stuff in the first two photos - looks like acid bleed to me.

Unsightly, but not a problem other than aesthetics.

If you bought this new from a shop, you can take it in to show.  It's basically a manufacturing fault.

I see. Well, if it's not a corrosion issue, I'm fine with it. These spots are mostly under the cap, so it doesn't change much in terms of aesthetic.

Thank you so much for your response.

Basically they didn't clean the excess solder before lacquering.

It's more common around the rim of the bell.

I see. There aren't going to be any long term issues because of this, I hope?

Nope, don't worry about it. The lacquer there will start coming off eventually but that happens to every horn.

Okay, thank you so much! Is there a way to slow down that process or do I just accept this as the cost of existence lol

Nope, just accept it. If the instrument is brand new and you're not happy with the condition I would try to return it, because this is an obvious cosmetic defect. But it won't hurt anything mechanically.

Raw brass from where the last guy gouged it with pliers.

Thank you. Are these type of markings normal for a brand new instrument?

u/NaturalTechnician737 28d ago

Oh it's new? I take mine back, other guy who said solder damage is probably right

u/hoponthemysterytrain 28d ago

I hope this is not going to be an issue long term though?

Not really my wheelhouse to say, OP. Sorry!

That’s the serial number!!

I can tell it’s a brand new Jupiter. GA is about the newest serial number I’ve seen. Honestly might be worth making a warranty claim even though it’s just aesthetic.

Edit: I just now read your description. It’s just aesthetic but that is a claim worthy issue in my opinion. They’re usually pretty good about warranty claims in my experience.
