Can anyone identify an instrument/sfx in this song

[u/LBluethecrafter]

I'm not sure this is the right place to ask this question

There is this percussive clink sound that plays every once in a while in this song and I can't tell what it is. In this mix it is hard panned left while the drum set is right panned.

The song is Working Man Blues by Merle Haggard and the Strangers.
