Thank you Bill! An inspiration!
Attached are two photos showing the new “door honker” installed. It is quite effective! This is only possible in rural settings as the honking would be a problem in suburban or urban neighborhoods. The squeeze horn makes an ideal “door bell” when other alternatives don’t work including wireless doorbells (can’t transmit through metal doors and siding), iron door knockers (not loud enough), or banging one’s hand against the door. A compressed air powered horn doesn’t have any charm. The squeeze horn is perfect! The rubber bulb is “holstered” in a 6″ round float that has been cut out to receive the bulb and protect it from the sun. The horn is tethered to the post using a brass chain.
