AB, it actually looks like "spotted metal" which is used to make organ pipes. It's composition varies a lot by vintage and manufacturer.Looks like galvanized sheet metal..
Galvanize processes usually leave a crystalline surface structure.

Naaaaaaaaaaa, i just happen to know a little about pipe organs, and a bit more about metal. Spotted metal is not an unfamiliar sight for me, even though it can have a variety of appearances.
While we're discussing it, it occurs to me that the spotted metal would have some useful damping properties for HF horns. As far as metals go, it's pretty soft and dense usually being a mixture of tin and lead, but can be found with a variety of other metals also mixed in.
Now for the real kicker, as i look closer i'm starting to doubt spotted metal and actually think it's a form of hammertone paint.
It looks like some chipping on the edges, i just wouldn't dare testify to it either way.
