Very rare, early 19th century, well used wooden herb grinder. Most herb grinders were metal. This is the only wooden herb grinder I have ever seen. The trough and the base were carved from a single piece of wood, and both the trough and the wheel show signs of wear.
Well used
Trough is 13 1/2″ long and 2 3/4″ tall, height of wheel in trough is 6″
