Dear Dr McCormick,
I donít know of any other bits or examples of tooth wear, but there are
examples of cheek-pieces that were probably used with bits. I recently
worked on an assemblage from a ring-ditch site in Cheshire, thought to be
of Bronze Age date, that included a cheek-piece worked from a red deer
antler tine. I can send a photo by e-mail if it would be helpful.
