Brass Instruments

Inspect bell, bore, valves or rotors, slides, braces, finish, maker marks, and serial together.

Brass condition cannot be reduced to shine. Start with the complete instrument outside its case, then read the bell and accessible bore, valve or rotor surfaces, slides, braces, water keys, finish wear, engraving, and serial evidence.

Read the label on the evidence

Complete does not mean certified.

The Exchange can require views, structured answers, ownership of uploaded media, and named specialist review before publication. Those controls improve the listing record; they do not prove authenticity, legal title, physical possession, sound, value, or future condition.
