I have a bell called a "Double Dinger" made by Mirrcycle. IT doesn't look exactly like the one you've pictured above... it looks like the one shown here: https://www.rei.com/product/723519/m...er-incredibell. The trigger does not operate with a spring, instead it rotates around the outer circumfrence.

Pros: makes a perfect "I'm a bicycle" sound..... I mostly use it to say "hello" to people when I'm too out of breath or too far away to use my voice.
Also, you can swing the lever around the bell to any position.

Cons: It's not super loud, but I have a couple louder bells if I want something louder.

I don't remember what I paid for it, but it was very affordable. My friend has one of those all brass bells, and it's loud and (as mentioned above) classy. But it's just a single "ding".
