Spitfire Spitfire Horns

I have a MkI Spitfire and need to install the horns. Some books show a horn fuse, but it isn't noted as an in-line fuse. I'm wondering if the "horn fuse" on the schematic is a relay. I think it would be a good thing to be able to announce the presence of the my car in certain situations. The schematic confuses me. T.T.
 
I'll have to dig around the house and see if I can find my original US-market Spitfire 4 Owners Handbook, which is the ONLY factory (or other, AFAIK) publication with the proper wiring diagram for a US-spec early Spitfire. At the moment, I honestly don't remember if the early cars had either a relay or an inline fuse, but I suspect you could easily get by without one if there's nothing there at present.
 
I do not have a horn relay on my Mk I. I think I do have one in-line fuse behind the dash, but not sure what it's for.
