When I was a kid that would have sounded incredibly old to me. Now the trombone i play semi-regularly is about 100 years old and I never think about it. It’s only about 20 years older than the one I learned on which was passed down from my uncle, and it’s in better shape so it just seems normal to me.

Edit: I looked up the serial number, it’s from 1925, so next year I can say 100 year old.
