Yoder horns were only used on the B models 1955-59 HUMMER models. There were actually 2 different horns used on these models

69001-55 This was the Dual-Tone Goose horn Used on 1955-56-57& 58 models
69001-55A This is the single tone used only in 1959.

The only differences in the 2 horns are the reed.
