I used to be part of a Yahoo Train Horn Forum many years ago and that’s where I got my current horn, but been too busy to do anything more with it. I am looking sell my K5LA to a good home lol!! I also have a Graham White valve that will go with the horn. If anyone is interested give me a shout and hopefully we can work something out, I currently only have photos of the horn the valve is mounted in the truck, but the manifold is powder coated.
Thank you
John
