What horn is inside the 1968 Valiant?

[Schyrjajew]

Hey guys.
I bought a 1968 Plymouth Valiant, made in Switzerland.
Last week I saw that there are no horns in the engine compartment. They took them out...
What are the original horns from?
Whats the name? Does anyone have a picture?

Thanks

This is what they look like and where they are mounted
