What was the trumpet made out of in the past?
Probably brass. Just like the saxophones, trombones, and the like. That's why directors call it the brass section. The inside of the trumpet, the valve part, is a slightly different material, able to slide up and down with just a touch of valve oil for lubrication. The keys, which is the part the trumpeter pushes down, are topped with a good looking material, usually ivory. Then you have the mouthpiece. Some, as I understand, are made of pure silver, but that could be a rumor. Certainly of a bright material resembling silver. Get in touch with Conn, the makers of brass instruments. Probably have a webside.
