I'm grateful to Clive Bridger of the LVR-RömerMuseum in Xanten for pointing me in the direction of a privately produced book on horse equipment (mainly, but not exclusively, bits), available as a free PDF download (No.100). All in Italian, but the pictures are sumptuous and worth it (cut and paste into Google Translate if you need the gist). Needless to say, mostly unprovenanced.
