Frequency Ringer Identification Markings?
« on: December 09, 2017, 10:12:44 PM »
Working with a frequency ringer. At 20 Hz, I get clapper movement but weak. Moving the gongs fully inward, I get a soft ring. My first thought is the ringer is near 20 Hz or a near a harmonic of 20Hz.

While cleaning the reed area, I noticed stampings on the reed holder. Within the circle, there is a large "3" and above that what looks like "54 ~" possibly indicating this to be 54 Hz frequency ringer. A 54 Hz ringer would be near the 3rd harmonic of 20 Hz and as such some movement of the clapper,

Has anyone else looked closely and seen these types of stamping, or does someone know for sure and can confirm the companies that produced frequency ringers use these stampings to identify the ringer?
