lot of antique vintage solid brass ball tips for horse harness hames

Lot of four vintage old brass ball finial tips for horse harness collar hames. These horse hames tops are solid brass. They measure from about 6 1/2" to 7" long over the tails. The two finial balls on the left look to us like a pair (although the length is slightly different). One of the hame tips is missing the tail. These all measure about 1 5/8" across the balls.

These are all out of an estate near Portage, Wisconsin (the Amish region in Wisconsin). They have a patina of age and tarnish.
