Spartan air horn

I have a 82 Campbell 24ft cc, with a Spartan air horn. Does anyone know where i can get replacement parts so I can get them to work?

Not sure about Spartan but when I was going through my rebuild I ran into a lot of road blocks (as in the companies that built a lot of stuff for our boats are no longer around) so I improvised and improved and went with a system based around this
