"Y1" component designation?

I don't thing the Y prefix is for a crystal. Like was stated I thought
it was for a resonnant filter, i.e ceramic or other type. These tend to
have 3 legs instead of a crystal's 2.

I have an old 1970 ARRL Handbook and it has crystals listed as Y. I
also have a 2002 handbook and it has crystals and ceramic resonators
listed as Y. To me, anything with a Y designation is a resonant
component that is either a crystal or ceramic resonator.
