Octave key pads don’t have resonators. I don’t even think they were snapped in on these horns, just shellac or “pad glue”.
That’s a beautiful instrument. If you have the ability, take it apart and use some cleaner on the body - Pledge furniture polish or perhaps a very mild automotive cleaner polish, on a clean cloth. A lot of that dull spotting on the body will clean right up, and the spots where lacquer is missing will be less noticeable.
While I agree with cleaning and perhaps conditioning the pads, I also concur that you should take it to a good tech as soon as possible. One that has experience on vintage horns. That’s a forever horn you got there. Congratulations, and I’m a bit jealous!
