My 1958 14-19-2 has no evidence of a warning bell or horn installation for the landing gear. The Operating and Maintenance Flightbook has a wiring diagram showing a "throttle switch" on the engine side of the firewall, and showing a landing gear "warning horn" (not a bell) wired to that switch. Does anyone have a photo of the throttle switch, as installed, and of the gear warning bell or horn, and its location?
