Hello everyone. I have a klaxon model 21. The horn works but I am missing the adjustment part. I am attaching a picture of the missing part circled in red. If anyone can help me figure out what part goes there it would be much appreciated.I have tried different springs but they seem to just push it out farther out when I need adjustment in.

I figured it out. A spring goes on the end that I was missing and the adjustment is 2 nuts that slide the entire back section forward and backwards. Here is a quick video of the sound after I got it adjusted. https://youtube.com/shorts/z3LvQCJWMGM? ... TPZZ8MMwo5
