Is this just lacquer wear?

Anything to be concerned about with the little greenish-blackish spots on that inner bow?
Would stripping the lacquer off the entire horn be the only way to get a more uniform finish?
Thanks!

photo access would help!

It was working for me. I re-copied and pasted the photobucket link all the same. Should be working now!

That is oxidation under the lacquer. It could be caused by little breaks in the lacquer allowing air to tarnish the brass. If you want it "purdy" then you would need to have it over-hauled or keep up on it with polishing... That would eventually wear away the lacquer.

I've seen this on almost-new horns. Apparently something was splattered on the horn before the lacquer was applied to cause extreme thin-ness of the lacquer or loss of adhesion.
Like another poster said.... about all you can do is either strip it or allow it to just 'wear away'.
I had a year-old horn in here a few days ago that had red-ish spots on the inner surfaces of the large tubes. There was no lacquer at all on those spots. It wasn't 'rot'.... just lack of lacquer.

What horn is it?
Looks like it's also on the slides. That would be a lot of work to spot-buff with a Dremmel or similar tool, but if you need a project . . . . .
Try buffing down to the oxidation, cleaning with a laquer thinner, and then spraying with an aerosol laquer.

The horn is my Bach 869 "Mercedes." From the front, the horn still looks nice and shiny, the back side, for whatever reason, is the side with most of the scratches and "lack of lacquer."
