cantle

It was a genuine western, with high horn and high cantle and two cinches, but much reduced in every dimension.

A steak had been cut off the full breadth of it—a monstrous cantle from out its fair proportions.

The term Cantle is sometimes used for either plate, but it is generally accepted as the name for the rear peak.

Immediately outside, in the passage, appeared Grandfer Cantle singing in concert with those still standing in front of the house.
