I rebuilt my 33 horn by retrofitting the internals out of new 12v bull horn, some modification required to the mechanical operation. The perimeter mounting holes exactly line up and the cover will fit.

Model 51.. thanks for all your hard work to clarify this topic. I have the B 13815 spartan and it is a major PITA to adjust and set. The others look a lot simpler.. can you offer any comments in comparisons, do the others actually work better? Also, another post suggested any "replacement" can be made using same parts from 33-36. Can you confirm this?

Thanks

I'm frustrated that I can't get any one of my horns to work. It looks like such a simple device with so few parts but I must be missing something or overlooking things. I put this project aside for a bit but will have to get back on it soon. I've done a little search trying to find someone to help with no success so I'm a bit frustrated, hence my decision to work on other more pressing restoration projects for now.

I don't have any idea about replacement parts. I've heard that the reproduction horns aren't very good but I don't have any experience with those either.
