Reply to "AF 561 Diesel Horn Billboard"

KD,

You're right, that's from the maintenance manual, but it does talk about adjusting the volume and tone of the horn and the diagram shows you where the adjustment screw is. There doesn't appear to be a knob.

My 1949 Instruction Manual pre-dates the 561, and Tom Barkers repair guide doesn't seem to cover the 561.

Anybody out there got a copy of the 561 instruction sheet?
