Just bought a used Mt Vernon Bach from 1955 and it was advertised in IMMACULATE condition with a recent chemical cleaning and valve alignment. There is a nice "pop" when you pull the first and third valve slides, but nothing when you pull the second? What could be wrong?

Your 2nd valve slide could be loose from wear or someone over polishing it. The second valve could be worn also.
