Honda E., thank you for posting a picture of your ringer! Seriously, frequency ringers are rare these days, and just finding a picture of one is a challenge. In the future when this comes up again, someone will have that pic to refer to.
They are rare because people toss them in the trash after they put in a standard ringer. The only folks who save them are hard core pack rats, err, I mean collectors.
