Conn and Dupont "Four in One" Cornet, 1879
This "Four in One" (Eb, C, Bb and A) cornet had original finish,
but it was in rough shape and was missing many original parts.  
The valve pistons were loose, split and bent from previous abuse.
 The owner, Wayne Collier, has a couple of others in better
original condition but wanted this one to be brought back as close
to original as possible, including reproducing the missing shanks,
crooks, waterkeys etc.  I have a very
similar example in my
collection, so I could replicate the missing parts very closely.  It
required new silver plating and I was determined to preserve the
original surface finish which was not a high polish but not a sand
blasted satin finish either.  This was accomplished by keeping the
polishing to the absolute minimum needed.  After silver plating, it
was finished off with rottenstone.

This turned out to be one of the best playing Conn and Dupont
cornets that I've come across.
