I've No Longer Got the 'orn

[Falcon 269]

I have a Nautilus air horn separated into compressor and horn sections.  The horn is mounted under the reg/rec on a simple alloy bracket, the compressor lives where the AIS block used to be under fuel tank.  Rubber hose connects the two components.  I fitted a relay to the original horn wires and ran a separate fused 12v feed from the battery to the compressor.  Loud and invisible.
