The horns take a lot of juice and the wires to them on my '48 are big honkers (sorry). I'd be surprised if there isn't a relay somewhere. The little wires to your horn button are enough to throw the relay but it seems to me that they would burn up if they were used to power the horn. At least, that's the case on my '48.
