This kit will allow you to repair a broken shaft on most French ceramic herb mills. The kit includes a plastic shaft, a spring, a wooden handle, a spring support plastic washer and a handle support plastic washer. (Your mill might have a plastic handle instead of a wooden one.) Please take a look at the picture to see if this is the part you need. The shaft is 4" long and about 9/16" diameter at the top and 1/2" at the bottom.
