Finding k5la off of train horns

Does anyone know anything about finding old k5la that came off of trains and restoring them? Where to find them and restore them. I have a hOrn kit now 4 bells with 150psi compressor 5 gallon tank but I want a set of k5la and don’t have a whole lot of money to spend
