One constant problem is the Austin Seven diaphragm rusts or the Diaphragm breaks down due to wear and age.
We have offered a great new stainless steel Diaphram for many years now that also gives back that great hoo-waaa sound.
Austin 7, Austin Seven, A7, and Morris cars often were fitted with a Rist Horn. You now can get that great sound back.








We do not sell other parts only supply the Diaphragm.
