It was not uncommon on many cars to replace (even augment) existing or conventional horns with either air horns, or the similarly loud (but not requiring a compressor) fanfare horns, including those made by Bosch. Depending on how much current the compressor draws, aftermarket kits also included a relay which may be additional. My Bosch catalog page of the era, showing conventional and fanfare horns (but no air horns) also has wiring diagrams for
all their horns, and they
all appear to be driven off a relay. I guess you really don't want all that current going through the horn ring switch.
Air horns were also common as standard equipment on many European cars of the era. My aunt's late 1960's Taunus (German Ford) sedan had them as standard. Not only was the lighting brighter on European cars (what with H4 halogens etc.)of the 1960's apparently they were louder too!
